ABSTRACT:
An interstage coupling network is provided comprising a series connection of an even number of reactive elements coupled between the input and output terminals of the interstage network, a junction point of said series connection of inductors being coupled to a signal reference potential via a first reactive shunt element. A series connection of oppositely-poled switching diodes is coupled in parallel with a portion of said series connection of reactive elements, the junction between the series-coupled diodes being coupled to the signal reference potential via a second reactive shunt element. A third reactive element is coupled between the network output terminal and a point on the series connection of reactive elements which is remote from the input terminal of the network.
