Abstract :
Multi-octave contiguous channel multiplexers are a key component in EW systems, since they provide the front-end signal sorting. The paper describes advances in the development of broadband, low-loss, selective, lowpass, highpass and bandpass filters and contiguous channel multiplexers from 500 MHz to 26.5 GHz, in the form of suspended substrate stripline (SSS) realisations in particular to increased bandwidth/channel and increased band-edge selectivity. The paper also discusses a novel range of low-loss, selective, broad-band filters, recently designed using lumped-element technology to provide a high performance over 20 MHz to 1.5 GHz.
