High frequency range and high power frequency hopping filter

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.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a frequency hopping filter. Background technique [0002] High-power frequency-hopping filters belong to band-pass filters. The disadvantages of current high-power frequency-hopping filter designs are large insertion loss, poor filter selectivity, and poor heat dissipation of components, resulting in short working life; selectivity for high-frequency bands Not good, the sensitivity of the filtered signal is not high, and the integration of the high-power frequency hopping filter is not high, the product is bulky, and the manufacturing cost is high.
