Typical Applications
This HMC-ALH310 is ideal for:
• Point-to-Point Radios
• Point-to-Multi-Point Radios
• Military & Space
The HMC-ALH310 is a three stage GaAs HEMT MMIC
Low Noise Ampli er (LNA) which operates between
37 and 42 GHz. The HMC-ALH310 features 22 dB of
small signal gain, 3.5 dB of noise gure 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 ampli er 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.
