摘要
Abstract
A design method of combiner based on common cavity is presented to reduce the size of combiner. First, coupling coefficient of each passband can be calculated by generalized Chebyshev function. Then circuit simulation software AWR is used to optimize the circuit model and extract the coupling matrix of the combiner.Finally ,the physical dimensions are extracted with electromagnetic field simulation software HFSS and a combiner used for base station was made. The measured results show the IL is less than 1.6 dB in the passband of 820 MHz to 880 MHz and the out-of-band rejection level is larger than 40 dB at the frequency of 890 MHz. The measured results matches with the simulation well and the combiner has high practical value.关键词
