SWITCHED MULTIPLEXER

摘要

This invention is about the switched multiplexers used for adaptive filtering in systems operating in signal dense environments such as electronic warfare systems. The aim of this invention is to design a switched multiplexer with lower input/output return losses and having lower level of destructive interaction between channels compared to the known examples.

主权项

1. A switched multiplexer comprising:
at least one RE input; a first power splitters dividing the RE input into two;
a first block, which fulfills the filtering function in the preferred channels, which consists of two identical odd channel non-contiguous multiplexers containing two identical contiguous multiplexers (A), a plurality of diplexers and a plurality of resistors and are combined symmetrically through attenuators and switches;a second block, which fulfills the filtering function in the preferred channels not covered by the first block, which consists of two identical even channel non-contiguous multiplexers (B) containing two identical contiguous multiplexers, a plurality of diplexers and a plurality of resistors and are combined symmetrically via attenuators and switches.
