General Description
The MAX2042A single, high-linearity upconversion/
downconversion mixer provides up to +33dBm input
IP3, 7.25dB noise figure, and 7.2dB conversion loss for
1600MHz to 3900MHz GSM/EDGE, CDMA, TD-SCDMA,
WCDMA, LTE, TD-LTE, WiMAXK, and MMDS wireless
infrastructure applications. With an ultra-wide 1300MHz
to 4000MHz LO frequency range, the IC can be used in
either low-side or high-side LO injection architectures for
virtually all 1.7GHz to 3.5GHz applications (for a 2.5GHz
variant tuned specifically for low-side LO injection, refer
to the MAX2042).
In addition to offering excellent linearity and noise
performance, the IC also yields a high level of component
integration. This device includes a double-balanced
passive mixer core, an LO buffer, and on-chip baluns
that allow for single-ended RF and LO inputs. The
IC requires a nominal LO drive of 0dBm, and supply
current is typically 140mA at VCC = 5.0V or 122mA at
VCC = 3.3V.
The MAX2042A is pin compatible with the MAX2042
2000MHz to 3000MHz mixer. The MAX2042A is also pin
similar with the MAX2029/MAX2031/MAX2033 650MHz
to 1550MHz mixers, the MAX2039/MAX2041 1700MHz
to 3000MHz mixers, and the MAX2044 2300MHz to
4000MHz mixer, making the entire family of upconverters/
downconverters ideal for applications where a common
PCB layout is used for multiple frequency bands.
The MAX2042A is available in a compact, 20-pin TQFN
package (5mm x 5mm) with an exposed pad. Electrical
performance is guaranteed over the extended TC = -40NC
to +85NC temperature range.

ABSOLUTE MAXIMUM RATINGS
Note 1: TC is the temperature on the exposed pad of the package. TA is the ambient temperature of the device and PCB.
Note 2: Based on junction temperature TJ = TC + (BJC x VCC x ICC). This formula can be used when the temperature of the
exposed pad is known while the device is soldered down to a PCB. See the Applications Information section for details.
The junction temperature must not exceed +150NC.
Note 3: Junction temperature TJ = TA + (BJA x VCC x ICC). This formula can be used when the ambient temperature of the PCB is
known. The junction temperature must not exceed +150NC.
Note 4: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

Upconversion/Downconversion Mixer with LO Buffer
Functional Diagram
Detailed Description
When used as a high-side LO injection mixer in the
2300MHz to 2900MHz band, the MAX2042A provides
+33dBm of IIP3, with typical conversion loss and noise
figure values of only 7.2dB and 7.25dB, respectively.
The integrated baluns and matching circuitry allow for
50I single-ended interfaces to the RF and the LO port.
The integrated LO buffer provides a high drive level to
the mixer core, reducing the LO drive required at the
IC’s input to a -6dBm to +3dBm range. The IF port incor-
porates a differential output, which is ideal for providing
enhanced 2LO - 2RF performance.
Specifications are over broad frequency ranges to allow
for use in GSM/EDGE, CDMA, TD-SCDMA, WCDMA, LTE,
TD-LTE, WiMAX, and MMDS base stations. The device
is specified to operate over a 1600MHz to 3900MHz
RF input range, a 1300MHz to 4000MHz LO range,
and a 50MHz to 500MHz IF range. The external IF
components set the lower frequency range (see the
Typical Operating Characteristics for details). Operation
beyond these ranges is possible (see the Typical
Operating Characteristics for additional information).
RF Input and Balun
The IC’s RF input provides a 50I match when combined
with a series DC-blocking capacitor. This DC-blocking
capacitor is required as the input is internally DC shorted
to ground through the on-chip balun. When using an
8.2pF DC-blocking capacitor, the RF port input return
loss is typically 17dB over the 2300MHz to 2900MHz
RF frequency range. A return loss of 14dB over the
3000MHz to 3900MHz range is achieved by changing
the DC-blocking capacitor to 1.5pF.
For applications spanning the 1700MHz to 2200MHz
frequency range, a 12nH shunt inductor can be used
in conjunction with a 1.8pF DC-blocking capacitor to
provide a typical return loss of 12dB. See the Typical
Application Circuit and Table 1 for details.
LO Inputs, Buffer, and Balun
With a broadband LO drive circuit spanning 1300MHz to
4000MHz, the device can be used in either low- or high-
side LO injection architectures for virtually all 1.7GHz to
3.5GHz receiver and transmitter applications. The LO
input is internally matched to 50I, requiring only a 2pF
DC-blocking capacitor. A two-stage internal LO buffer
allows for a -6dBm to +3dBm LO input power range. The
on-chip low-loss balun, along with an LO buffer, drives
the double-balanced mixer. All interfacing and match-
ing components from the LO inputs to the IF outputs are
integrated on-chip.
High-Linearity Mixer
The core of the device is a double-balanced, high-
performance passive mixer. Exceptional linearity is
provided by the large LO swing from the on-chip LO buffer.
IIP3, 2LO - 2RF rejection, and noise-figure performance
are typically 33dBm, 72dBc, and 7.25dB, respectively.
Differential IF Ports
The device has a 50MHz to 500MHz IF frequency range,
where the low-end frequency depends on the frequency
response of the external IF components.
The device’s differential IF ports are ideal for providing
enhanced 2LO - 2RF performance. The user can connect
a differential IF amplifier or SAW filter to the mixer IF
port, but a DC block is required on both IF+/IF- ports to
keep external DC from entering the IF ports of the mixer.
To characterize the part, an external MABACT0069 1:1
transformer is used to transform the 50I differential IF
interface to 50I single-ended. Its loss is included in the
data presented in this data sheet. This transformer also
supplies a needed IF pin ground return for the on-chip
circuitry. If a ground return is not available on the IF pins,
the return is achievable through some off-chip resistance
to ground or large-value inductors. A 1kI to ground
on each IF pin can be used for such an application.
In addition, the IF interface directly supports single-
ended, AC-coupled signals into or out of IF+ by shorting
IF- to ground and using a 1kI resistor from IF+ to ground.

Applications Information
Input and Output Matching
The RF input provides a 50I match when combined
with a series DC-blocking capacitor. Use an 8.2pF capac-
itor value for RF frequencies ranging from 2000MHz to
2900MHz. Use a 1.5pF capacitor value to match the
RF port for the 3000MHz to 3900MHz band. For RF
frequencies in the 1650MHz to 2250MHz range, use
C1 = 1.8pF and L1 = 12nH. The LO input is internally
matched to 50I, so use a 2pF DC-blocking capacitor
to cover operations spanning the 1300MHz to 4000MHz
range. The IF output impedance is 50I (differential).
For evaluation, an external low-loss 1:1 (impedance
ratio) balun transforms this impedance down to a 50I
single-ended output (see the Typical Application Circuit).
Reduced-Power Mode
The device includes a pin (LOBIAS) that allows an exter-
nal resistor to set the internal bias current. A nominal
value for this resistor is given in Tables 1 and 2. Larger-
value resistors can be used to reduce power dissipa-
tion at the expense of some performance loss. If Q1%
resistors are not readily available, substitute with Q5%
resistors.
Significant reductions in power consumption can also be
realized by operating the mixer with an optional supply
voltage of 3.3V. Doing so reduces the overall power
consumption by up to 42%. See the 3.3V Supply AC
Electrical Characteristics tables and the relevant 3.3V
curves in the Typical Operating Characteristics section to
evaluate the power vs. performance tradeoffs.
Layout Considerations
A properly designed PCB is an essential part of any
RF/microwave circuit. Keep RF signal lines as short as
possible to reduce losses, radiation, and inductance.
For the best performance, route the ground pin traces
directly to the exposed pad under the package. The PCB
exposed pad MUST be connected to the ground plane
of the PCB. It is suggested that multiple vias be used to
connect this pad to the lower-level ground planes. This
method provides a good RF/thermal conduction path for
the device. Solder the exposed pad on the bottom of the
device package to the PCB.
Power-Supply Bypassing
Proper voltage-supply bypassing is essential for high-
frequency circuit stability. Bypass each VCC pin with the
capacitors shown in the Typical Application Circuit and
see Table 1.
Exposed Pad RF/Thermal
Considerations
The exposed pad (EP) of the device’s 20-pin TQFN
package provides a low thermal-resistance path to the
die. It is important that the PCB on which the device is
mounted be designed to conduct heat from the EP. In
addition, provide the EP with a low-inductance path to
electrical ground. The EP MUST be soldered to a ground
plane on the PCB, either directly or through an array of
plated via holes.
