Low-Cost X-Band MIC Parametric Amplifier

Abstract
An X-band MIC parametric amplifier using planar printed circuit techniques which result in low-cost and high reliability has been developed. Design of a microstrip four-port circulator and parametric amplifier stage on a low-loss YIG substrate, a 31-GHz microstrip pump source on teflon-fiber glass, and a pump source at the same frequency in integrated fin-line are described.
