摘要
Abstract
A miniaturized semi-lumped balun based on Marchand balun was proposed. Loading terminal capacitors and resonant capacitors were employed in this structure to reduce the electric length of the coupling line. The size of the balun was further reduced due to the multilayer structure based on LTCC technology. The proposed structure was analyzed in detail using even-odd mode analysis method and some design curves were achieved. The balun with the size of 2.5 mm×2.0 mm×1.0 mm was simulated and fabricated by using the A6-M material. The results show that parameters of the fabricated balun are the amplitude imbalance of ±0.5 dB and the phase imbalance of ±10°, with over the 511 of-15 dB in 2.7-2.9 GHz. The reason for variance between the simulation value and the test value was analyzed.关键词
