HMC621LP4 / 621LP4E
RFIC DOWNCONVERTER SMT, 0.9 - 1.6 GHz
v01.0708
General Description
Features
Functional Diagram
The HMC621LP4E is a highly integrated downcon-
verter IC that operates from 0.9 to 1.6 GHz. The
HMC621LP4E incorporates a high dynamic range,
single-balanced mixer core with integrated RF, LO and
IF ampliers, making it ideal for compact transceiver
applications in Cellular//3G & LTE/WiMAX/4G. This
versatile converter RFIC operates with a low LO input
power level of only 0 dBm, provides 30 dB conversion
gain, and exhibits +33 dBm output IP3. The integrated
RF amplier provides for an overall noise gure of
only 4.5 dB.
High Output IP3: +33 dBm
Low Noise Figure: 4.5 dB
Low Input LO Drive: 0 dBm
High LO to RF Isolation: 45 dB
High Conversion Gain: 30 dB
24 Lead 4x4mm SMT Package: 16mm2
Electrical Specications, TA = +25 °C, IF= 200 MHz, LO= 0 dBm, Vbias [1] = +5V [2]
Typical Applications
The HMC621LP4 / HMC621LP4E is ideal for:
• Cellular/3G and LTE/WiMAX/4G
• BTS & Infrastructure

9 LOIN This pin is AC coupled
and matched to 50 Ohms.
12 VddLO Power supply for LO amplier.
An external RF bypass capacitor is required.
14 MIXIF
This pin is DC coupled. For applications not requiring
operation to DC this port should be DC blocked
externally using a series capacitor. Choose value of
capacitor to pass IF frequency desired. For operation to
DC, this pin must not sink/source more than 40 mA of
current or failure may result.
15 IFIN This pin is DC coupled.
An off chip DC blocking capacitor is required.
17 IFOUT IF output and DC Bias (Vcc) for the output stage.

Evaluation PCB
The circuit board used in the application should
use RF circuit design techniques. Signal lines
should have 50 Ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
Hittite upon request.
