Title: Multiplex superheterodyne radio receiver
Inventor: INOUE TAKANORI
IPC: H04B1/26
Filed: 1989-12-29
Abstract: PURPOSE:To eliminate the need for the installation of a local oscillation circuit at every frequency conversion circuit by giving each component signal from plural band pass filters to plural mixer circuits as a local oscillation signal. CONSTITUTION:An output signal composed of a fundamental wave component whose frequency is fo and harmonic components whose frequencies are an integral number of multiple of the frequency fo is always sent from a local oscillation circuit 20 to a 1st local oscillation frequency filter 4b and a 2nd local oscillation frequency filter 7b. Then a 1st local oscillation frequency filter 4b extracts a 5th high frequency which is 5fo from the sent output signal and sends it to a 1st mixer circuit 4a. On the other hand, the 2nd local oscillation frequency filter 7b extracts a 3rd harmonic wave 3fo from the sent output signal and sends it to a 2nd mixer circuit 7a as a 2nd local oscillation signal. Thus, it is not required to provide a local oscillation circuit at every frequency conversion circuit.

Title: Input signal attenuation circuit and communication circuit
Inventor: ISHII KATSUHIRO
IPC: H04B1/10
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To effectively reduce the causes to cross modulation or the like with a simple configuration without affecting the impedance characteristic or the like of a surrounding circuit by providing an interruption means whose one terminal is connected to a signal line through which a signal with a plurality of frequencies is transmitted and a signal power bypass means that is connected to the other terminal of the interruption means and connects a prescribed ratio of signal power to ground to the title communication circuit. SOLUTION: When a desired wave and an undesired wave (disturbing wave) of a certain level are simultaneously given to a mixer 5 from an antenna 1, intermodulation distortion is caused. In the case that a signal with a high level is given to the mixer 5, a switch 8 is closed to connect a diode 9 and the mixer 5 electrically. Thus, the signal with the high level is supplied to the diode 9 to decrease an input level to the mixer 5. Thus, even when an intercept point of the mixer 5 is low, the effect of the intermodulation distortion on reception sensitivity is reduced since the absolute input power is lowered.
