Resumen/Abstract
In this paper, a novel highly linear circularly polarized active antenna with gain control is presented. In this approach, the antenna serves as a 90º hybrid and the active part has been implemented using a branch line coupler as the 90º input hybrid circuit, and two PHEMT based amplifiers. The amplifiers are based on a new strategy for gain control with low distortion.
