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 fi gure 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 passivated 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.
