Abstract

A high efficiency two stage MMIC power amplifier has been designed to meet the requirements of a 64 element transmit phased array antenna operating at 8.2 GHz. The array will provide a high speed data communication link for the NASA GSFC new millennium program. The array is to be installed on the Earth observing scientific satellite EO-1 scheduled for launch in 1999. The two stage MMIC amplifier cell includes an on chip gate bias reference. It provides 23 dB small signal gain, 45% PAE, and requires only 1 square millimeter of die area
