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 Amplifier (LNA) chip which operates

from 6 to 20 GHz. The HMC565 features 22 dB of small

signal gain, 2.3 dB of noise figure 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

fixture connected via two 0.025 mm (1 mil) diameter

bondwires of minimal length 0.31 mm (12 mil).

Noise Figure: 2.3 dB
