摘要：

A novel 4 stage 3.2GHz similar to 50GHz ultra wideband YIG-Tunable-Filter. The coupling ring is made of patented technology and precision machining. The cavity shielding is realized by gold mesh pressure bonding. The detuning isolation is higher than 80dB; the staged magnetic circuit structure is used. The magnetic circuit is composed of two different materials. The 3.2GHz similar to 50GHz ultra wide band YIG filter has the characteristics of high linearity and low hysteresis, and the linearity is less than +/- 80MHz in full band. A new way to describe the linearity of the filter is presented in this paper.
