Suspended Substrate Filters and Multiplexers

Abstract

The different configurations which may be used for broadband lowpass and highpass filters will be discussed for applications from 0.5 - 40 GHz. Diplexer design and their application to broadband multiplexers will be considered with examples of practical devices. Due to the limitations of loss, narrow band bandpass and bandstop designs have restricted applications. However, one application in contiguous switched multiplexers will be considered in detail where the dissipation loss characteristic plays a very important role in the overall device performance. Such an N channel switched multiplexer may assume anyone of 2N states within 30 ns. Finally, other special classes of networks such as constant phase difference networks will be discussed with applications to frequency discriminators.
