Abstract
A pHEMT Q-band low noise amplifier (LNA) for radio astronomy applications is designed, fabricated and measured. This LNA exhibits a bandwidth from 27 to 45 GHz with the small signal gain of 25 dB, and with the noise figure below 3.1 dB. The total power consumption is only 9 mA, and the figure-of-merit (FOM) is 34.2 (GHz/mW), which is highest compared with the previously published LNAs.
