General Description
Functional Diagram
The HMC566 is a high dynamic range GaAs PHEMT
MMIC Low Noise Amplifier (LNA) chip which operates
from 29 to 36 GHz. The HMC566 provides 20 dB of
small signal gain, 2.8 dB of noise figure and output
IP3 of 23.5 dBm across the operating band. This self-
biased LNA is ideal for hybrid and MCM assemblies
due to its compact size, slightly positive gain slope,
single +3V supply operation, and DC blocked RF I/O’s.
All data is measured with the chip in a 50 Ohm test
fixture connected via two 0.025 mm (1 mil) diameter
bondwires of minimal length 0.31 mm (12 mil).
