Abstract: A high frequency super regenerative direct detector includes a power supply and a signal detecting circuit arrangement electrically connected thereto. The signal detecting circuit arrangement, which is a transistor control system, includes a high frequency by-pass circuit, a LC tank circuit configured to be tuned at a pre-tuned frequency to receive an incoming signal to generate an oscillator frequency, ranging from 850 MHz to 960 MHz, a quenching circuit generating a quenching frequency, and a transistor circuit device configured to incorporate oscillator frequency into the quenching frequency in such a manner that when the incoming signal matches the pre-tuned frequency, a timing to achieve a saturated level of the quenching frequency is faster than no signal period, and a modulation frequency of the incoming signal is detected out from the signal detecting circuit arrangement.
