The ALP291 from Northrop Grumann is an E-band Low Noise Amplifier MMIC that operates from 71 to 86 GHz. It provides a small signal linear gain of 28 dB with a noise figure of less than 3.2 dB and has a P1dB of 3 dBm. This amplifier is based on the 0.1 μm InP HEMT process and has a microstrip topology. It is fully passivated to ensure rugged and reliable operation and has a bond pad and backside Ti/Au metallization, which is compatible with conventional die attach, thermos-compression and thermos-sonic wire bonding assembly techniques. It requires a DC supply of 1.3 V and consumes 25 mW of power. This amplifier is available as a die that measures 1.6 sq. mm and is ideal for point-to-point digital radios, point-to-multipoint digital radios and SATCOM terminal applications.
