Gain: 13 dB
P1dB Output Power: 13 dBm
Single Supply Voltage: +3.5V @ 70mA
Output IP3: +23 dBm
50 Ohm matched Input/Output
24 Lead 4x4 mm SMT Package: 16mm
Electrical Specications, TA = +25° C, Vdd1 = Vdd2 = +3.5V, Idd = 70 mA
Typical Applications
This HMC962LC4 is ideal for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios
• Military & Space
• Test Instrumentation
The HMC962LC4 is a self-biased GaAs MMIC Low
Noise Amplier housed in a leadless 4x4 mm ceramic
surface mount package. The amplier operates
between 7.5 and 26.5 GHz, providing 13 dB of small
signal gain, 2.5 dB noise gure, and output IP3 of
+23 dBm, while requiring only 70 mA from a +3.5 V
supply. The P1dB output power of +13 dBm enables
the LNA to function as a LO driver for balanced, I/Q
or image reject mixers. The HMC962LC4 also fe-
atures I/Os that are DC blocked and internally mat-
ched to 50 Ohms, making it ideal for high capacity
microwave radios and VSAT applications.

[2] Circuit Board Material: Rogers 4350 or Arlon 25FR
List of Material for Evaluation PCB EVAL01-HMC962LC4 [1]
The circuit board used in this application should
use RF circuit design techniques. Signal lines
should have 50 Ohm impedance while the pack-
age ground leads and exposed paddle should be
connected 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 board should be mounted
to an appropriate heat sink. The evaluation circuit
board shown is available from Hittite upon request.
