General Description
Functional Diagram
The HMC-ALH310 is a three stage GaAs HEMT MMIC
Low Noise Amplifier (LNA) which operates between
37 and 42 GHz. The HMC-ALH310 features 22 dB of
small signal gain, 3.5 dB of noise figure and an output
power of +12 dBm at 1dB compression from a +2.5V
supply voltage. All bond pads and the die backside
are Ti/Au metallized and the amplifier device is fully
passivated for reliable operation. This versatile LNA
is compatible with conventional die attach methods,
as well as thermocompression and thermosonic
wirebonding, making it ideal for MCM and hybrid
microcircuit applications. All data shown herein is
measured with the chip in a 50 Ohm environment and
contacted with RF probes.
