Abstract
The development of the Schottky barrier diode along with microwave integrated circuit techniques makes possible miniature high performance microwave detectors. This paper describes a low noise microwave integrated circuit mixer using Schottky barrier diodes and reactively terminated image with a 500 MHz thin film IF preamplifier. The entire mixer-IF preamplifier occupies an area of only 0.38 square inches and has a noise figure of 6.7 dB.
