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