Abstract
A microwave amplifier using a varactor diode for improving the receiver noise figure is described. The amplifier is a stable, 2-diode type, with a coaxial signal circuit, a lumped element idler circuit, and a waveguide pump circuit. The design provides a 50-MHz bandwidth at 20-dB gain, and a noise temperature of 200°K. KEYWORDS: Amplifiers, Broadband, Design, Microwave Relay Systems, Signaling, Signal-to-Noise Ratio, Ultra-High Frequency.
