Abstract
A quasioptical amplifier cell suitable for power-combining arrays is presented. Orthogonally polarised patch antennas are coupled to the input and output of a resistive-feedback MESFET amplifier. A simple polarimetric reflectometer was developed to test the amplifier cell which solves the problem of imperfect isolation between transmitting and receiving horns and the DC offset problem of quadrature detectors. A peak effective isotropic power gain (EIPG) of 17dB was measured at 4.2GHz with 1% bandwidth which is limited by patch antennas.Keywords
