RF receiving circuit
Fig 2 shows receiving circuit / comparator circuit. Career signal (waveform ⑧) input from U4-6pin outputs
career wave (waveform ③) with U4 LTC5507 high frequency amplifier/detect IC. Career wave is amplified
by U5 / U6 operational amplifier TC75W60, and outputs waveform ⑩, ⑪. Waveform ⑩ is input to U7
Comparator TC75S59 non inverting input. Other waveform ⑪ inputs to U7 inverting input, and outputs Rx
data (waveform ⑬) to U8-1pin and 2pin.
