HMC634LC4
v03.0514
GaAs PHEMT MMIC DRIVER
AMPLIFIER, 5 - 20 GHz
General Description
Features
Functional Diagram
The HMC634LC4 is a GaAs PHEMT MMIC Driver
Amplier in a leadless 4 x 4 mm ceramic surface
mount package which operates between 5 and 20
GHz The amplier provides up to 21 dB of gain, +29
dBm Output IP3, and +22 dBm of output power at 1 dB
gain compression, while requiring 180 mA from a +5V
supply. The HMC634LC4 is an ideal driver amplier
for microwave radio applications from 5 to 20 GHz,
and may be biased at +5V, 130 mA to provide lower
gain with optimized PAE. The amplier’s I/Os are DC
blocked and matched to 50 Ohms with no external
matching required.
