1. , a kind of modulation-carrier communication device, it is characterized in that taking a kind of limiting modulation circuit of margining amplitude technique modulated carrier, make the waveform generation changes in amplitude of the carrier wave of band signal not by modulation signal, its amplitude limit system circuit has two kinds of forms:

  • the parallel connection type limiting modulation circuit is by diode D 1, D 2, resistance R 1, R 2, R 3, R 4, capacitor C 1, C 2, C 3Form, wherein some resistance can replace with triode, and load and modulator are connected in parallel;

    The tandem type limiting modulation circuit is by switching diode D 1, D 2, resistance R 1, R 2, R 3, R 4, R 5, R 6Form, wherein some resistance can replace with triode, and load and modulator are connected in series.
