Title: Intermediate frequency block
Inventor: YAMASHITA KIYOBUMI
IPC: H03J3/04
Filed: 1983-01-20
Abstract: PURPOSE:To cancel the temperature drift by using an elastic surface wave resonator commonly used as a local oscillator part to a control part, and securing the follow-up of the local oscillator frequency of the elastic surface wave to the temperature drift of the frequency of a Nyquist filter for the elastic surface wave. CONSTITUTION:An elastic surface wave device 25 consisting of an elastic surface wave resonator 251 and a Nyquist filter 252 is set between a tuner part and a wave detecting part. With this device 25, the amplitude characteristics of the filter 252 are shifted to the low temperature side if the peripheral temperature of the device 25 increases owing to use of the resonator 251 provided to a local oscillator circuit. Thus (fv-DELTAf) is obtained (fv: normal amplitude characteristics of the filter 252). In this case, both the filter 252 and the resonator 251 are set on the same level and therefore the normal amplitude characteristics fr of the resonator 251 are shifted to (fr-DELTAf). Then, the carrier frequency 27 of the tuner output follows the carrier frequency (fv-DELTAf) of the filter 251. Thus the temperature drift of the filter 252 can be cancelled.
