ABSTRACT:
A low-power, self-quenching superregenerative receiver utilizes a single-port SAW device coupled to an RF oscillator to establish the frequency of oscillation at the output of the RF oscillator. A diode detector is coupled from the oscillator output for detecting a predetermined amplitude of the oscillation output signal. A time-constant circuit is coupled from the signal detector for generating an oscillator quench signal when the oscillator signal is detected and the oscillator quench signal has a predetermined duration set by the time-constant circuit. A feedback circuit couples the oscillator quench signal to the RF oscillator to cause the RF oscillator to switch to a non-oscillating condition only during the predetermined duration of the RF oscillator quench signal. The RF oscillator then switches to the oscillating condition and the system repeats itself.
