Abstract :
This paper presents a novel structure design of millimeter broadband mixer. The LO signal input from the rectangular waveguide to suspended microstrip line and the RF signal from a rectangular waveguide to a fin line. The Suspended microstrip lines and finline with a pair of diodes rested between them constitute a balanced mixing circuit. Through the simulation of the millimeter-wave broadband mixer, it owns a 75-105GHz operating frequency, and its conversion loss is better than 12dB. The isolation among the three ports is also excellent. In addition, the mixer´s structure is very simple and easy processed.
