Embodiment Construction

[0018] In order to make the object, 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.

[0019] like figure 1 As shown, Embodiment 1 of the present invention provides a high-power frequency hopping filter, in which an analog circuit unit and a digital control circuit board 40 are arranged in a heat-conducting housing; the analog circuit unit includes two resonant modules 10 (i.e. double tuned loop), a switching diode array circuit 20, and a high voltage driver 30. The resonant module 10 is composed of a resonator 11 and an impedance matching device 12. The resonators 11 of the two symmetrical resonant modules are connected through a coupler 50, and the resonators 11 of the two resonant modules pass through the switches in turn. The diode array circuit 20 , the high voltage driver 30 are connected with the digital control circuit board 40 .

Abstract

The invention discloses a bounce frequency filter comprising heat conducting shell bodies, an analog circuit unit and a digital control circuit board, wherein the analog circuit unit comprises at least two syntonic modules, a switch diode array circuit and a high-pressure drive; the syntonic modules are connected by a coupler and are respectively connected with the digital control circuit board bythe switch diode array circuit and the high-pressure drive and the analog circuit unit and the digital control circuit board are respectively arranged in different cavities of the heat conducting shell bodies. In this way, the electromagnetic interference between internal electronic elements is prevented and the height or the volume of a product is reduced. The product has good filtering effect and quick heat dispersion and can keep long-time working stability.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a frequency hopping filter. Background technique [0002] The frequency hopping filter is generally installed at the output port of the power amplifier of the transmitter, which is used to effectively filter out useless transmission clutter frequencies and prevent wireless interference signals from other transmitters from entering the local transmitter. The frequency hopping filter is a bandpass filter device. The disadvantages of current high-power frequency-hopping filter design are that the insertion loss is large, the filtering effect is not good, and the heat dissipation of the components is poor, resulting in a short working life. To dissipate heat; the existing high-power frequency-hopping filter products are large in size and high in manufacturing cost. Contents of the invention [0003] The embodiment of the present invention provides a frequency hopping filte...
