Abstract
A system for processing signal communications between a frequency translation module and an integrated receiver decoder. According to an exemplary embodiment, the decoder and the frequency translation module comprise a signal processing apparatus comprising an input for receiving an frequency shift keyed modulated signal, an amplifier having negative feedback coupled to said input, wherein said input is further coupled to a first source of reference potential and a second source of reference potential; and a tank circuit coupled between said differential amplifier and an output. More particularly, the amplifier may comprise a first transistor having a first collector, a first emitter and a first base coupled to a signal source wherein said first base is further coupled to said first collector and a second transistor with a second base, a second emitter coupled to said first emitter, and a second collector, wherein said second collector is coupled to a bandpass filter and said bandpass filter is further coupled to an output.
