Novel aviation frequency band receiving circuit
The invention discloses an aviation frequency band receiving circuit. A single-chip multiband frequency modulation and amplitude modulation receiving circuit is added on the basis of a VHF band interphone, thereby not only having standard interphone functions, but also being a standard four-band rad...

| description | The invention discloses an aviation frequency band receiving circuit. A single-chip multiband frequency modulation and amplitude modulation receiving circuit is added on the basis of a VHF band interphone, thereby not only having standard interphone functions, but also being a standard four-band radio, and high-frequency standard aviation signals can even be received on the basis of all original functions by means of a short waveband receiving function in the four-band radio and via comprehensive utilization of VHF136-174MHz narrowband frequency synthesis circuits. The aviation frequency band receiving circuit disclosed by the invention has the characteristics of simple circuit and powerful functions, can be used as a shortwave radio receiver and can also receive standard aviation signals within the range of 118-135.975MHz, and is high in sensitivity, good in receiving selectivity and strong in anti-interference ability.
