Title: Radio receiver of frequency conversion type
Inventor: SASAKI SUSUMU
IPC: H03G3/20
Filed: 1983-06-23
Abstract: PURPOSE:To improve the saturation characteristic without having a bad influence upon an overall noise factor by reducing the gain of a radio frequency amplifier and increasing the gain of an intermediate frequency amplifier at the time when the saturation of the output level of the intermediate frequency amplifier is started. CONSTITUTION:When an RF input level is increased, the output level of an intermediate frequency amplifier IFA4 is increased linearly; and when this output level exceeds a certain level, a frequency converter MIX and succeeding stages of the IFA4 start being saturated to generate a transmission distortion. A level detector 5 detects this saturation start level and drives a switch 1S to turn on an attenuator 1A and drives a switch 4S to turn off an attenuator 4A. In this case, if values of the attenuation quantity of the turned-on attenuator 1A and the attenuation quantity of the turned-off attenuator 4A are set to the same value, they are cancelled mutually, and the output level of the IFA4 is not changed. Consequently, the saturation of the MIX and the IFA is avoided, and a bad influence upon the whole of a receiver is prevented.
