In order to meet the phase consistency requirements of YIG-tuned filter in modern electronic equipment, factors was analyzed affecting its phase characteristics and the phase variation within passband summarized from perspective of engineering design. Multi-channel integrating design techniques was applied to get optimum solution to phase consistency, solving problems as hysteresis, nonlinearity, drift and other key factors affecting the phase consistency. Simulation optimization design of multi-channel integrated coupling structure, integrated magnetic circuit and precise compensation and other important aspects was introduced in this paper. Four-channel amplitude and phase consistency YIG-tuned band pass filter was designed, with operating frequency of 2 to 6GHz, amplitude consistency of ± 1.5dB, phase consistencyof ± 8 °, meeting the design requirements.
