Title: Psk demodulating circuit
Inventor: TANAKA YASUTO
IPC: H04L27/22
Filed: 1985-12-11
Abstract: PURPOSE:To perform correct PSK demodulation by adding a high frequency switch circuit which does not supply a composite signal to a demodulating circuit during the period of an FM modulated signal but supplies the composite signal to the demodulating circuit during the period of a PSK modulated signal. CONSTITUTION:The input signal from the input terminal of a receiver is supplied to not only the first band amplifier circuit 2 but also the second band amplifier circuit 6. This signal has required band amplified and is inputted to a high frequency switch circuit 7. The circuit 7 uses a double balanced mixer (DBM) and is turned on and off synchronously with the control pulse from a digital processing circuit 5 and selects only the PSK modulated signal and outputs it to a synchronous detecting circuit 8 and a carrier reproducing circuit 9. The circuit 9 eliminates a code component from the supplied signal to perform carrier reproducing and supplies a reproduced signal to the detecting circuit 8. The circuit 8 performs synchronous detection by signals supplies from the switch circuit 7 and the reproducing circuit 9 and performs PSK demodulation, and PSK demodulated audio data is outputted to PSK demodulated signal output terminal.

Filed: 1989-10-27
Abstract: PURPOSE:To obtain a desired directional pattern without lowering a circularly polarized wave characteristic by peripheraly surrounding a radiating element with a horn reflector, and forming a circular groove in the outer peripheral part of a reflection board on the bottom surface of this horn reflector. CONSTITUTION:The inner diameter of the horn reflection board in a horn reflector 17 is formed to be gradually large from a reflection board 16 to a tip opening position so that the radiation directivity of a helical radiating element 14 can be set corresponding to a parabola antenna.
