N A FILTER BANK RECEIVER. YIG FSL operation is discussed via a basic analytical model. In this study, transient response to pulsed RF signals, frequency modulated signals, small signal suppression and intermodulation product phenomena when two signals are simultaneously received, are also reported. Experimental results obtained agree with the analytical model. Extensive data are provided to facilitate design of YIG FSLs in filter bank receivers. Specific applications for YIG FSLs are present YIG FSL as a level normalizer, cascading YIG FSLs to obtain large limiting range, threshold level detection influenced by small signal suppression, and use of a YIG FSL to offset amplitude reduction of bandpass filters caused by a sweep signal. A filter bank receiver comprising YIG FSLs is presently under construction.
