ABSTRACT:
An improved multiplexer especially adapted for combining a plurality of microwave signal channels for transmission over a common transmission path is disclosed. A single "directional filter" multiplexer structure is utilized to combine contiguous or adjacent channels without resort to odd-even channel separation or additional equalization and/or compensation networks. By purposely extending the bandpass characteristics of preselected channel filters so that either or both of their cutoff frequencies extend substantially past their associated channel band edges and well into the reflection loss regions of the adjacent channel or channels the adjacent channel mutual interaction effect is exploited. The resultant interaction between the transmission characteristics of one channel and the reflection characteristics of the adjacent channel yields an overall transmission characteristic for each channel which meets the multiplexer loss, loss slope and group delay requirements while minimizing the need for equalizing or compensating devices.
