Abstract

The invention relates to a high-frequency and high-power IMPATT tube electrical parameter debugging device, which includes a mounting plate, a group of pin mounting holes and waveguide holes are arranged on the mounting plate, and the pin mounting holes are connected with positioning pins; an adjustment seat is provided, and one side of the adjustment seat is provided with The positioning hole matched with the positioning pin and the positioning groove matched with the outer contour of the tooling, and the other side is connected with the clamping device with adjustable tightness. The clamping device is provided with a through-hole slot corresponding to the position of the waveguide hole. Cooperate with the short-circuit piston; the adjustment seat positions the tooling part through the positioning pin and the positioning groove, and then is detachably and fixedly connected with the mounting plate, and the excitation source feeder of the tooling part is electrically connected with the excitation source module. The invention is simple in structure and easy to assemble, and combines the mechanical tuning of the short-circuit piston and the electrical tuning of the excitation source feed to realize the high-frequency power output of the IMPATT diode; by adjusting the tightness of the clamping device, the mechanical tuning thickness adjustment is realized, and the overall The operation is simple and easy, and the debugging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of millimeter-wave solid-state device detection, in particular to a high-frequency and high-power IMPATT tube electric parameter debugging device. Background technique [0002] IMPATT diodes use the semiconductor internal collision avalanche effect and carrier transit time effect to obtain dynamic negative resistance, which can generate oscillation under the action of an external circuit and output radio frequency power. It can be used in the development of solid-state oscillation sources for core devices in millimeter wave systems. With the improvement of the operating frequency of the millimeter-wave system, for high-frequency and high-power IMPATT tubes, the coaxial structure is difficult to achieve resonant output. Now an open structure based on the waveguide output bearing device is adopted, and discrete capacitors are used for impedance matching to reduce the set Total parameters, to achieve high-frequ...
