HMC565
GaAs PHEMT MMIC LOW NOISE
AMPLIFIER, 6 - 20 GHz
v02.0209
General Description
Features
Functional Diagram
The HMC565 is a high dynamic range GaAs PHEMT
MMIC Low Noise Ampli er (LNA) chip which operates
from 6 to 20 GHz. The HMC565 features 22 dB of small
signal gain, 2.3 dB of noise gure and has a consistent
IP3 of 20 dBm across the operating band. This self-
biased LNA is ideal for hybrid and MCM assemblies
due to its compact size, wideband performance, single
+3V supply operation, and DC blocked RF I/O’s. All
data is measured with the chip in a 50 Ohm test
xture connected via two 0.025 mm (1 mil) diameter
bondwires of minimal length 0.31 mm (12 mil).
