Bidirectional duplexer for polarised microwaves, particularly realised in monolithic technology on gallium arsenide

摘要

The invention relates to a novel bidirectional duplexer structure for the simultaneous transmission and reception of circularly polarised microwaves. …??According to the invention, the bidirectional duplexer is of the type intended to link a first set of two inputs/outputs (RF0, RF1; RF2, RF3) to a second set of two inputs/outputs (RF2, RF3; RF0, RF1), each input/output (RF0, RF1, RF2, RF3) of the duplexer being connected to the combining channel (20, 21, 22, 23) of a combiner/divider (12, 13, 14, 15), the two dividing channels (24, 25, 26, 27, 28, 29, 30, 31) of each combiner/divider (12, 13, 14, 15) each ensuring the link with one of the dividing channels (24, 25, 26, 27, 28, 29, 30, 31) of one of the combiners/dividers (12, 13, 14, 15) connected to an input/output (RF0, RF1; RF2, RF3) distinct from the opposite set of inputs/outputs (RF2, RF3; RF0, RF1) across distinct phase-shifting means (16, 17, 18, 19). …IMAGE…
