Abstract
The first 3*3 port balanced phase diversity receiver in which thermal noise has the same impact as in heterodyne receivers was realised although three preamplifiers are used. Experimental and theoretical results which prove the reduced impact of thermal noise compared with a conventional 3*3 port receiver are presented.
