摘要（英）：

The invention provides a wide band YIG electrically tunable filter. The wide band YIG electrically tunable filter is suitable for the technical field of electrically tunable filters, and comprises a shell, an upper magnetic electrode, a lower magnetic electrode and turning coils. The upper magnetic electrode and the lower magnetic electrode are fixed among the turning coils. The part, close to gaps, between the upper magnetic electrode and the lower magnetic electrode becomes thinner. The upper magnetic electrode and the lower magnetic electrode are formed through the combination of two materials. A magnetic circuit is formed by the shell, the upper magnetic electrode, the lower magnetic electrode and the turning coils. The frequency band of the wide band YIG electrically tunable filter is within the range of 3GHz-50GHz, the tuning linearity of the wide band YIG electrically tunable filter reaches 0.2 percent, and meanwhile the linearity of the wide band YIG electrically tunable filter is smaller than 100MHz.
