Embodiment Construction

[0014] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, Embodiment 1 of the present invention provides a high-frequency high-power frequency-hopping filter. In the metal casing, the cavity structure resonator is connected to the switching diode array circuit 3, the choke coil 4 and the frequency-hopping filter for controlling the frequency-hopping filter in sequence. The digital control circuit board 6 is connected; the cavity structure resonator is composed of two cylindrical conductors with a length of 1 / 4 wavelength and two impedance matching coils arranged in an independent cavity. Specifically, the signal input end of the filter is sequentially connected to the impedance matching coil 11 , the cylindrical conductor 21 and the switch diode array circuit 3 . The input signal is co...

Abstract

The invention discloses a high frequency range and high power frequency hopping filter. In a metal shell, a resonator in a cavity structure is sequentially connected with a switching diode array circuit, a choke coil and a digital control circuit board for controlling frequency hopping filtering and consists of a first cylindrical conductor, a second cylindrical conductor, a first impedance matching coil and a second impedance matching coil which are arranged in independent cavities and have the length of a quarter wavelength. By adopting the resonator in the special cavity structure, the high frequency range and high power frequency hopping filter has excellent filtering effect in the high frequency range, favorable filtering selectivity and less insertion loss. A high power switching diode array with a large heating value is welded on a silver-plated copper plate, and the silver-plated copper plate is connected with a heat conducting plate of the metal shell, thereby the heat dispersion is faster.
