A miniaturized duplexer with high isolation is designed in this paper. The coupling coefficient of branch filter is solved by Generalized Chebyshev function, and the circuit model is simulated and optimized by MATLAB and ADS. Finally, the physical dimensions are extracted by HFSS, and the simulation model of combiner is established and optimized. The experimental results show that the loss of the miniaturized combiner is less than 1.5dB, and the out of band rejection is greater than 40dB@1550-1580MHz&1600-1625MHz .The simulation results verify the rationality and feasibility of the design.
