44 GHz Monolithic Low Noise Amplifier

The design, fabrication, and performance of a single-stage 44 GHz monolithic HEMT low noise amplifier are described. The chip includes a single heterojunction HEMT with matching and biasing circuits. Greater than 5 dB gain was measured from 43.5 to 45.5 GHz and a noise figure of 5 dB with the associated gain of 5.5 dB was achieved at 44.5 GHz. The chip size is 1.25mm x 1.0mm.
