  • Direct microwave demodulator of PSK signals with automatic gain control
    Patent number: 4559499
    Abstract: The microwave reception chain according to the invention comprises a direct microwave demodulation device comprising a demodulation circuit associated with an oscillator operating at the microwave carrier frequeny, controllable to coincide in phase with the carrier received. The demodulation circuit comprises a separator coupled to the input for the received signal and connected to two symmetrical mixers which respectively receive the carrier from the oscillator and the same carrier shifted through 90.degree. which are available at the output of a coupler having a phase shift of 90.degree., the outputs of the mixers being connected to low-pass filters restoring the demodulated digital sequences. The reception chain comprises an automatic gain control circuit in the base band and a phase calculator receiving the demodulated digital sequences.
