Microwave signal generating circuitry - provides two signal components from circular polarised microwave signal in hybrid and supplied to separation filter

摘要

The circuitry is designed to produce microwave signals in a common waveguide (E) which includes a hybrid (H), dividing a signal to be converted from a circularly polarised microwave signal into two signal components of equal and max. power. A polarising and distributing cross-over network (PW) with two inputs (1, 2) is supplied with the signal components. One output opens into a common waveguide, switching the paths so that the two parts are shifted by 90 deg. w.r.t. one another. In one of the separate paths a bridging guide (BW1, BW2) possesses a first hybrid (H1) which divides the signal part into two branches tuned to its frequencies by the units (F1, F2) and a second hybrid (H2) which combines the two branches, feeding them to the inputs of the distributing guide (PW). ADVANTAGE - Reduced power losses. Limited max. field strength.
