LOW NOISE FRONT ENDS FOR TACTICAL UHF RADIO RELAY RECEIVERS

Abstract

Certain new devices were examined from the standpoint of low noise front end design for the proposed radio set AN/GRC-103, operating in the range 220 to 700 mc. Parametric amplifiers are not suitable for subject radio set because of size, weight and operational complexity. Tunnel diode amplifiers are not practicable due to the need for broadband ferrite circulators in the 220 mc to 700 mc frequency range. Tunnel diode downconverters look promising and should be capable of providing noise figure of about 5 db without using ferrite devices.
