摘要

In this paper, a synthesis and inaccuracy analyses of an active power splitter (PWS) is proposed. It is based on the active cell composed of a Field Effect Transistor in cascade with shunted resistor at the input and the output (resistive amplifier topology). The PWS inaccuracy versus resistance tolerances is suggested by using stochastic method. Furthermore, with the proposed topology, we can control easily the device gain while varying a resistance. The active PWS simulation results show a rather constant 0° output phase (0°±5°), insertion losses above -1.5dB and an excellent isolation below -30dB for all three ports, for a bandwidth from 0.3GHz to 3.3GHz.
