Design of K-Ka Band MMIC Broadband Passive Mixer Chip
This paper describes the design of a wideband passive mixer chip for K2Ka band MMIC.The chip adopts a passive double balanced mixer structure,and the local oscillator and RF baluns are spiral Marchand baluns.The key technical indicators have shown excellent performance,with a chip size of only 1.15mm×0.8mm×0.1mm,achieving miniaturization.By careful design and optimization,the mixer chip exhibits excellent performance such as low loss,high isolation,and high linearity over a wide frequency range,effectively meeting the demand for high-performance RF devices in modern communication and radar systems.
