Problems solved by technology

[0005] However, there is a big problem in this kind of drive module at present. A triode die and a field effect die are welded on a ceramic board, but the triode die and the field effect die are easily damaged, and Field effect modules and ceramic inductors remain intact
Since it is impossible to repair the damaged tube core, the entire RF power supply equipment will no longer work, which will cause great economic losses to the manufacturers of the equipment, ranging from 70,000 to 80,000 yuan to as many as 100,000 yuan.

Abstract

The invention discloses a radio-frequency power supply drive module, which comprises a heat dissipation substrate; the radio-frequency power supply drive module is characterized in that the heat dissipation substrate is provided with a ceramic inductor, a field effect module, a triode and heat dissipation silica gel; a circuit board covers the heat dissipation substrate; the ceramic inductor, the field effect module and the triode all are in energized connection with the circuit board; a field effect tube is arranged on the bottom surface of the circuit board; and the top of the field effect tube is in close contact with the heat dissipation silica gel.

Description

technical field [0001] The invention belongs to the field of electronics and relates to a radio frequency power drive module. Background technique [0002] At present, in the field of RF power supply, the drive modules used include ordinary drive modules and stereo drive modules: [0003] Ordinary drive module: it is a planar structure, all electronic components are welded on the PCB (printed circuit board), the bottom of the power amplifier (field effect tube) is installed on the radiator (the PCB in this area should be hollowed out), and its pins Welded on the PCB; our country and some foreign companies usually use common drive modules. In this way, after the module is damaged, it can be repaired; but the PCB area used is large and the space occupied is relatively large. In the current situation where the focus is on how much radio frequency power can be produced per unit volume, and whoever produces the most radio frequency power per unit volume can win, the use of this...
