Receivers
• GSM & 3G & LTE/WiMAX/4G
• MIMO Infrastructure Receivers
• Wideband Radio Receivers
• Multiband Basestations & Repeaters
Broadband Operation with no external matching
Industry’s Most Compact Solution, 4x4 mm2 QFN
Package
High-side and Low-side LO injection Operation
Wide IF Frequency Range
High Input IP3 of +25.6dBm @ 2200 MHz
Power Conversion Gain of 7.9 dB
Input P1dB of 12 dBm
SSB Noise Figure of 9 dB
55 dBc Channel-to-Channel Isolation
Dedicated Enable Pins for IF & LO ampliers
Single-ended RF & LO input ports
The HMC990LP4E is a high linearity, dual channel down-
converting mixer optimized for multi-standard diversity
receiver applications that require low power consump-
tion and small size. The HMC990LP4E features new
wideband limiting LO ampliers to achieve an unprec-
edented RF bandwidth of 700 MHz to 3500 MHz. Unlike
conventional narrow-band downconverter RFICs, the
HMC990LP4E supports both high-side and low-side LO
injection over the entire RF frequency band. The RF and
LO input ports are internally matched to 50Ω.
The HMC990LP4E integrates LO and IF ampliers with
enable functions, LO and RF baluns and high linear-
ity passive mixer cores with bias control interface. The
balanced passive mixer combined with high-linearity IF
amplier architecture of HMC990LP4E provides excel-
lent LO-to-RF, LO-to-IF, and RF-to-IF isolations. The
HMC990LP4E provides a very low noise gure of 9dB,
and high IIP3 of +25.6dBm allowing device to be used in
demanding wideband applications. The HMC990LP4E’s
input IP3 can be further improved by external matching
for narrow-band applications. The HMC990LP4E has
typical less than 1.5W power consumption which can
be optimized through external bias control pins. The
HMC990LP4E also features a very fast enable control
interface for to be used for power saving in Time Division
Duplex (TDD) applications. The HMC990LP4E is housed
in a RoHS compliant 4x4 mm2 leadless QFN package.

HMC990LP4E
BROADBAND HIGH IP3 DUAL CHANNEL DOWNCONVERTER,
0.7 - 3.5 GHz
v06.0114
Application Information
The HMC990LP4E is a broadband dual channel, high dynamic range, high gain, low noise, high-linearity downcon-
verting mixer designed for covering RF frequencies from 700 MHz to 3.5 GHz. The HMC990LP4E’s low noise and
high linearity performance makes it suitable for a wide range of transmission standards, including LTE, CDMA, GSM,
MC-GSM, W-CDMA, UMTS, TD-SCDMA, WiMAX applications.
The HMC990LP4E offers an easy-to-use and complete frequency conversion solution for diversity and MIMO receiver
applications in a highly compact 4x4 mm2 QFN package. The HMC990LP4E greatly simplies the design of diversity
and MIMO receiver applications by increasing the integration level and reducing the number of required circuit ele-
ments thereby reducing cost, area, and power consumption.
Principle of Operation
The HMC990LP4E has two identical, symmetrical double-balanced passive mixers. These mixers are driven from a
common single-ended LO input that is broadband matched to 50 Ω and requires only a standard DC-blocking capaci-
tor. The single-ended LO input is converted into differential through the on-chip integrated balun followed by a LO
driver stage. The differential signal is divided into two differential paths and each mixer is driven by a separate LO
amplier.
The HMC990LP4E’s single-ended RF inputs are converted into differential through the on-chip integrated baluns.
The single-ended RF inputs are internally broadband matched to 50 Ω and require only standard DC-blocking capaci-
tors. However, the HMC990LP4E’s RF inputs can be externally matched for narrow band application frequency with a
simple matching network including a series inductor and a shunt capacitor to further improve the performance. Please
refer to the application circuit for narrowband RF input matching for the detailed information.
The HMC990LP4E’s IF ampliers are designed for differential 200 Ω output impedance. A few external components
are required at these IF outputs for the broadband frequency response as recommended in the application circuit.
Please refer to the IF output interface section for more information.
The HMC990LP4E requires 5V and 3.3V supply voltages and external bias voltages. Bias voltages generate reference
currents for the IF and LO ampliers. 3.3V supply voltage and the external bias voltages can be generated from 5V
supply voltage to operate with a single supply. Please refer to the single supply operation section for more information.
The reference currents to the LO ampliers and IF ampliers can be disabled through LO_EN and IFA1_EN, IFA2_EN
pins respectively. If the EN pins are connected to LOW or left unconnected, the part operates normally. If the EN pins
are connected to HIGH, the LO ampliers and IF ampliers are disabled.
Single Supply Operation
The HMC990LP4E requires 5V and 3.3V supply voltages and the external bias voltages. The external bias voltages
except VGATE1, VGATE2 pin voltages are already generated from 5V supply voltage on evaluation board (see applica-
tion circuit). These bias voltages can be optimized by series resistances with appropriate values from the 5V supply to
the bias pins (VCS1, VCS2, LO_BIAS1, LO_BIAS2). The resistor values on VCS1, VCS2 and LO_BIAS1, LO_BIAS2
traces on evaluation board are 130 Ohms and 150 Ohms respectively. Refer to the VCS Interface and LO_BIAS Interface
section for more information.
The nominal VGATE1, VGATE2 pin voltages are 4.8V that is applied externally. However VGATE1, VGATE2 pin voltages
can be tuned between 4.7V and 5V for optimization of Input IP3 and conversion gain performances. After VGATE1,
VGATE2 pin voltages are optimized, these pin voltages can be generated from 5V supply by changing the values of
series resistors, R14 and R15. Refer to the VGATE interface section for more information.

Figure 1. Interface to generate 3.3V for VDD_LO1 and VDD_LO2 pins from 5V Supply.
The 3.3V supply voltage for the LO ampliers can be generated from 5V supply voltage by adding 20 Ohms resistors
between VDD_LO1, VDD_LO2 pins and 5V supply voltage. VDD_LO1 and VDD_LO2 pins are shorted and con-
nected to VDD_LO1 test point on evaluation board, hence a 10 Ohms resistor (Rvdd_lo) can be added in series with
VDD_LO1 test point as shown in Figure 1. The resistor must have a power rating of 1/2W or more.
VGATE Interface
The VGATE1, VGATE2 pins are bias pins for mixer cores. The nominal VGATE1, VGATE2 pin voltages are 4.8V that is
applied externally. However voltage can be tuned between 4.7V and 5V for optimizing input IP3 and conversion gain
performances for desired frequency band. Higher IIP3 values can be obtained by increasing the VGATE1, VGATE2
pin voltages but this will reduce mixer’s conversion gain. Figure-2 shows the measured conversion gain and IIP3 for
four values of the VGATE1, VGATE2 pin voltages.

Table-1: Resistor values for different
VGATE pin voltages
After the VGATE voltage is tuned for optimized IIP3 and conversion gain performance, the VGATE pin voltage can
be generated from 5V supply voltage by changing the value of series resistors, R14 and R15 from 0 Ohm to an ap-
propriate value.
Table-1 shows the typical resistor values that need to be added in series with VGATE1, VGATE2 pins for different
VGATE voltages.A ne tune for R14 and R15 resistors can be needed if a better t is required.
VCS Interface and LO_BIAS Interface
The VCS1, VCS2 pins are bias pins for IF ampliers on each channel and set the reference currents to these IF ampli-
ers. The VCS voltage is generated from the 5V supply by series resistances. Higher IIP3 values can be obtained by
reducing the values of these series resistances R28 and R29, which will increase the total supply current of the IF am-
pliers. Figure-3a shows the measured conversion gain and IIP3 vs. total supply current from the VDD_IF1, VDD_IF2
and VDD_IF test points at 1900MHz.
The LO_BIAS1, LO_BIAS2 pins are bias pins for LO ampliers and set the reference currents to these LO ampliers.
The LO_BIAS voltage is generated from the 5V supply by series resistances R26 and R27. Figure-3b shows the mea-
sured conversion gain and IIP3 vs. total supply current from the VDD_LO1 test point at 1900MHz.

External RF Matching
The HMC990LP4E’s RF inputs are internally broadband matched to 50Ω. RF inputs can be externally matched for
a specic RF frequency band of interest to further improve Input IP3 (IIP3). Matching RF inputs to a specic RF fre-
quency band can be easily accomplished by adding a series inductor and a shunt capacitor. See Table-4 for values of
the external matching components for corresponding RF frequency bands. Figure-4 shows the application circuit with
the external components on RF input pins.
LO_BIAS2 and VGATE1, VGATE2 pin voltages can be optimized for a specic RF frequency band by changing the
resistor values in series with these pins. Table-1 shows the resistor values (R14, R15) for corresponding VGATE pin
voltage. Table-4 shows the resistor value (R26) for recommended LO_BIAS2 pin voltage.

The HMC990LP4E’s differential IF output pins are biased at the 5V supply voltage through choke inductors as shown
in the application circuit. The default values of these choke inductors are 680nH. Figure-8 shows the measured con-
version gain vs. IF frequency where 1-dB IF bandwidth is around 470MHz and 3-dB IF bandwidth is above 700MHz.
Higher IF bandwidth values can be obtained by reducing the value of the choke inductors.
The baluns at the IF outputs are used to convert the 200 Ohms differential output impedance of HMC990LP4E to
single-ended 50 Ohms for characterization.
