    A Duplexer design technique will be described which uses nominal size cavities and a single additional lump circuit element per cavity to produce transmitter to receiver isolations far greater than that produced by the cavities themselves. The lumped circuit element produces a notch in the cavity response curve which may be moved along the curve. The original design work on these duplexers was con... View full abstract»

    This paper describes a new approach to a noise operated squelch utilizing a desensitizing loop to sustain operation over short fades. This feature also provides a sharp demarkation between the operate and non-operate condition and minimizes "squelch tail". Another factor contributing to high performance is the use of an audio frequency desensitization input which prevents audio talk down during co... View full abstract»
