Abstract :
A miniaturized broadband marchand balun using low temperature co-fired ceramic (LTCC) technology is proposed in this paper. Modified Marchand balun has been chosen to broaden the bandwidth, and it covers the band of 0.95-2.15 GHz. A spiral broadside coupled stripline is adopted to realize the proposed miniaturized balun, and the overall size of the LTCC balun is only 2.0mm×1.25mm×0.95mm. Measured results match well with the computer simulation. The fabricated balun with symmetric structure achieves good VSWR and insertion loss performance, as well as excellent amplitude imbalance and phase difference.
