Title:
HARMONIC MIXER CIRCUIT AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2014/030350
Kind Code:
A1
Abstract:
[Problem] When a harmonic mixer circuit is used for a transmitter, it is difficult to sufficiently suppress generation of unwanted waves, and the properties of the harmonic mixer circuit are degraded. [Solution] This harmonic mixer circuit has: a main mixer for inputting a local emission signal and an intermediate frequency signal and outputting a high frequency signal; a reference mixer for inputting the local emission signal and outputting a reference signal; a sensor for inputting the reference signal and outputting a sensing signal; and a controller for applying a bias voltage to the main mixer and the reference mixer on the basis of the sensing signal.
