IPC: H03D7/14
Filed: 1978-07-04
Abstract: PURPOSE: To improve the cross modulation property, the mutual modulation property and the conversion loss each for the mixer circuit by installing the strip line with its terminal opened.  
     CONSTITUTION: Terminal-opened strip lines 4∼7 are installed to the anodes of diodes D 1  and D 3  as well as to the cathodes of diodes D 2  and D 4 . As a result, the reactance is reduced greatly for the mixer circuit to the local oscillation signal and the IF signal, and thus the current flowing to capacitors C 1 ∼C 4  plus diodes D 1 ∼D 4  increases. Accordingly, the bias voltage of diodes D 1 ∼D 4  can be set so as to secure the best cross modulation property for the mixer circuit, thus improving greatly boty the modulation loss and the mutual modulation property.
