Compact Multi-Stage Single-Ended Amplifiers for S-C Band Operation

Abstract

Design and fabrication of compact multi-stage single-ended feedback amplifiers operating from 2- 8 GHz are discussed. The nominal gains are 22 dB in the three-stage unit and 30 dB in the four-stage unit. Measured maximum VSWR's do not exceed 1.9:1. Noise figures, although not optimized, were below 7.6 dB and 8.4 dB, respectively.
