Functional Diagram
General Description
The HMC463LH250 is a GaAs MMIC pHEMT Low
Noise AGC Distributed Amplifier packaged in a
hermetic surface mount package which operates
between 2 and 20 GHz. The amplifier provides 13
dB of gain, 3 dB noise figure and 18 dBm of output
power at 1 dB gain compression while requiring only
60 mA from a +5V supply. An optional gate bias
(Vgg2) is provided to allow Adjustable Gain Control
(AGC) of 8 dB typical. Gain flatness is excellent at
0.5 dB from 2 - 14 GHz making the HMC463LH250
ideal for EW, ECM RADAR, test equipment and
High-Reliability applications. The HMC463LH250
LNA I/Os are internally matched to 50 Ohms and are
internally DC blocked.
