General Description
The HMC-ALH459 is a three stage GaAs HEMT MMIC
Low Noise Amplifier (LNA) which operates between
71 and 86 GHz. The HMC-ALH459 features 14 dB
of small signal gain, 4.5 dB of noise figure and an
output power of +7 dBm at 1dB compression from
two supply voltages at 2.1V and 2.4V respectively.
All bond pads and the die backside are Ti/Au
metallized and the amplifier device is fully pass-
ivated for reliable operation. This versatile LNA is
compatible with conventional die attach methods,
as well as thermocompression and thermosonic
wire bonding, 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.
