Title:
PASSIVE WIDEBAND FREQUENCY MIXER
Document Type and Number:
WIPO Patent Application WO/2020/125192
Kind Code:
A1
Abstract:
A passive wideband frequency mixer, comprising: a local oscillation balun, a radio frequency balun, a first diode D1, a second diode D2, a third diode D3, a fourth diode D4, an inductive compensation unit, and a grounded lossy inductance network. The described frequency mixer may achieve a mixer having a bandwidth ratio of less than 1:7, and points having deteriorated isolation are effectively inhibited without affecting full band frequency conversion loss; moreover, a local oscillator radio frequency port isolation metric is optimized within the full band, which may meet the needs for the application of a wideband frequency mixer in a communication system.
