Title:
MIXER FOR REDUCING LOCAL FREQUENCY SIGNAL GENERATED AT OUTPUT OF THE MIXER
Document Type and Number:
WIPO Patent Application WO/2020/145709
Kind Code:
A1
Abstract:
The disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related services. The disclosure provides a mixer including a first impedance connected in parallel to a mixer output transformer and configured to remove a primary local frequency component generated at an output of the mixer, and a second impedance connected in parallel to the mixer output transformer and configured to remove a secondary local frequency component generated at the output of the mixer, wherein the first impedance operates as a series resonator in a primary local frequency band, and the second impedance operates as a parallel resonator in a secondary local frequency band.
