Relevant key device information applied in this article:
In the
LM358
diagram, after the antenna receives the transmitted signal, it first passes through the filter composed of L1 and C1 to obtain the maximum gain for the 315Hz signal carrier frequency. The received signal is input into the high-frequency amplifier composed of VT1 through C2 for high-frequency amplification, so that the received signal has a larger signal amplitude. The signal output by VT1 is input into the super regeneration detection circuit composed of VT2, L0, C7, C7, C10, etc. for super regeneration detection. The detection signal output by VT2 is amplified by a two-stage amplification circuit composed of a dual operational amplifier circuit LM358, and then output from the output end and sent to the digital decoder for decoding.
