GaAs Amplifier Chip Boosts 71 To 86 GHz

May 13, 2009

The model HMC-ALH508 GaAs high-electron-mobility-transistor (HEMT), monolithic-microwave-integrated-circuit (MMIC) amplifier die from Hittite Microwave Corp. is ideal for automotive radar, military, and space applications from 71 to 86 GHz. The three-stage chip features 13 dB small-signal gain with 4.5 dB noise figure and +7 dBm output power at 1-dB compression. It operates from two supply voltages at +2.1 and +2.4 VDC while consuming only 30 mA supply current. The amplifier is fully passivated for reliable operation.
