Title: Microwave fm television signal receiver
Inventor: SHINKAWA TAKAO
IPC: H03J7/02
Filed: 1980-08-18
Abstract: PURPOSE:To contrive stabilization of a frequency of a local oscillator circuit in a single heterodyne type FM receiver by using a dielectric resonator, installing a balanced detecting circuit having a slope of reverse characteristic. CONSTITUTION:A dielectric resonator 18 is used for a local oscillator circuit 15 of a single heterodyne type receiver and a rotation controlling mechanism 29 which rotates a metallic screw 20 of the resonator 18, is used as a variable frequency mechanism for channel selection. This mechanism 29 controls the rotation of the screw 20 by an electric input. Balanced detecting circuits 21, 23 and 22, 24 having a slope of reverse characteristic detect an intermediate frequency FM signal. By comparing the absolute value of the pedestal level of this signal, the differential voltage signal, namely the detuning detecting signal, is used as a signal of an AFC circuit 28 and fed back to the control mechanism 29. In this way, stabilization of the frequency of the local oscillator circuit 15 is contrived.
