Description

technical field [0001] The invention relates to a high performance radio frequency receiver. Background technique [0002] At present, in the domestic automobile body wireless control system, in order to reduce the cost, the super-regenerative architecture is used in the receiver, and the radio frequency receiver composed of discrete components is used. Its performance is affected by many factors such as component errors and temperature drift. Coupled with the complexity of debugging and production quality control, its cost-effective advantage is gradually disappearing. Contents of the invention [0003] The purpose of the present invention is to provide a high-performance radio frequency receiver with good frequency characteristics and good anti-interference ability against the above-mentioned defects. [0004] The technical scheme of the present invention is: including a superheterodyne receiving chip, a crystal oscillator and a radio frequency circuit, the signal gene...
