摘要

disclosed is a drain bias circuit for high power fet adapted internally for use in an amplifier operating in the microwave domain.the circuit is characterized in that it comprises a line formed by a low impedance microbande, which has a length of.lambda.g / 2 at the frequency of operation,.lambda.g is the length of the guided wave in the microwave band, and two coils which are connected to the rf choke in the center of the micro strip line above a low input impedance.dividing into two routes to the drain current, which is sent to the center of the line, which makes it possible to maintain a load of 50. omega.while ensuring a proper bias of fet. the application for the electronics industry, especially for the construction of devices adapted for use on spacecraft.abstract: in join in figure 2.
