Abstract
A quasi-optical amplifier suitable for Gaussian-beam applications is presented. The amplifier is based on the integrated horn antenna and uses polarization duplexing to isolate the output beam from the input beam. A prototype hybrid amplifier is reported with a measured gain of 10.5 dB at 5.92 GHz. The amplifier design is uniplanar, is compact, and is compatible with the fabrication process of high-electron-mobility transistors (HEMTs) at millimeter-wave frequencies.<>
