BROADBAND HIGH FREQUENCY, MICROWAVE OR MILLIMETER WAVE MIXER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a broadband high frequency, microwave, or millimeter wave mixer system.SOLUTION: A mixer system includes a balun and a mixer. The balun has an unbalanced port 201, balanced ports 202, 203, first and second inductors 204, 205 coupled tightly and magnetically reversely each other, and a third inductor 206 not coupled magnetically with the first or second inductor. The mixer is connected with the balanced port of the balun. The balun including three inductors and the mixer are entirely integrated on a single substrate forming an integrated circuit.
