General Description
The HMC609LC4 is a GaAs PHEMT MMIC Low
Noise Amplifier (LNA) which operates from 2 to 4
GHz. The HMC609LC4 features extremely flat per-
formance characteristics including 20 dB of small
signal gain, 3.5 dB of noise figure and output IP3 of
+36.5 dBm across the operating band. This 50 Ohm
matched amplifier does not require any external
matching components. The HMC609LC4 is compatible
with high volume surface mount manufacturing
techniques, and the RF I/Os are DC blocked for fur-
ther ease of integration.
