Abstract

Ein Frequenzdiplexer, bei dem der Filterentwurf relativ wenig aufwendig ist, besteht aus zwei auf verschiedene Frequenzbänder abgestimmten Hohlleiterfiltern (2, 3) die beide an einer Stirnseite eines Rechteckhohlleiters (1) angekoppelt sind. Dabei sind die beiden Hohlleiterfilter (2, 3) über induktive Koppelblenden (4, 5), die in der Stirnseite des Rechteckhohlleiters (1), parallel zu dessen Breitseite (a), nebeneinander angeordnet sind, angekoppelt.
