Abstract

PURPOSE: To perform the frequency conversion of flat frequency performance not subject to the effect of the signal in image frequency, by absorbing and terminating one of the sum and difference of the input signal and the local oscillation signal with the non-reflection terminator and outputting other signal.
CONSTITUTION: The diplexer is formed with the input signal filter 2 and the image frequency filter 13, and the diode mount 3 is provided at the center. The filter 4 for conversion output signal is directly coupled with the mount 3 and the local oscillation signal filter 11 is placed in the mount 3. Thus, the input signal f1 and the local oscillation signal fL are inputted, enabling to pick up f1+fL and f1-fL, and one of them is absorbed and terminated with the non-reflection terminator 14 and only another signal can be picked up as output. Accordingly, without the effect of the signal in image frequency to the conversion output signal for desire, the frequency conversion having flat frequency performance over wide band can be made.
