Title

One- And Two-Stage Spatial Amplifiers

Abstract

This paper reports the design of nine HEMT, one- and two-stage spatial amplifiers which employ a common ground plane for receiving and transmitting port isolation and for heat sinking. By placing the spatial amplifier array in the near-field of the transmitting and receiving horns, a net gain of 8 dB was obtained. This paper also reports the first demonstration of a two-stage spatial amplifier constructed by employing near-field coupling of two single stage spatial amplifiers in free space. © 1995 IEEE
