Microwaves - phase shifter with o - or pi - phase shift.

摘要

Microwave phase-shifter able to produce, in response to a control signal 0, v, i.e. a phase shift is substantially zero, i.e. a phase shift is substantially equal to pi. / p & & p & it comprises a transistor fet 1 is preferably symmetrical, and operating in the amplifier assembly. The switching means in the low - frequency 18 make it possible, by reversing the polarizations on the source 3 and the drain 2, to reverse the fet 1. This results in a phase shift of pi of the microwave signal taken at the output 5 of the circuit.
