Embodiment Construction

[0025] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0026] The central section of the clamping and fastening device is shown in figure 1 shown. The clamping and fastening device includes an IMPATT tube snap ring, a locking ring, a fastening bolt and an adjusting stud. Tube external heat dissipation and other functions.

[0027] The three-dimensional schematic diagram of the assembly of the clamping and fastening device components is as follows: figure 2 As shown, the inner and outer diameters of the snap ring are concentric circles, and the inner diameter is slightly larger than the outer diameter of the IMPATT tube. The IMPATT diode is installed in the center ring of the snap ring, and the snap ring is assembled in the shell. The two ends of the snap ring are conical structures, which are nested with the tapered cavity of the shell and the locking ring, and then locked by fastening bolts fixed. An adjusting...

Abstract

The invention relates to an IMPATT (impact avalanche and transit time) diode clamping fastening apparatus, and aims to solve the problem existing in clamping and fastening of the IMPATT diode of a 3mm waveband microwave device based on an IMPATT diode technology. The apparatus adopts a unique clamping ring design; stress is applied to the tube shell bottom of the IMPATT diode through an adjusting double-screw bolt so as to realize position readjustment of the IMPATT diode; the two ends of the clamping ring adopt tapered structures, and the tapered parts are subjected to slotting processing; when stress is applied to a locking ring and the clamping ring through a fastening bolt, the tapered slotted position of the clamping ring is subjected to tiny deformation so as to tightly lock the IMPATT diode, so that the clamping and fastening function for the IMPATT diode is realized; a good thermal conducting function of the IMPATT diode to the outside is realized through reasonable type selection of the clamping material, control of the assembling gap, and control of the thermal conductivity of the apparatus; and compared with the existing IMPATT diode clamping and fastening apparatus, the MPATT diode clamping and fastening apparatus provided by the invention has the advantages of high adjustment, high reliability, high thermal conductivity, miniaturization, and the like.

Description

technical field [0001] The invention relates to the technical field of 3mm band IMPATT (ImpactAvalancheandTransistTime) tube microwave devices, in particular to an IMPATT diode clamping and fastening device, which can be applied to microwave devices such as 3mm injection lock amplifiers based on IMPATT tubes. Background technique [0002] Millimeter wave technology is one of the most popular topics in the field of microwave technology today, and has been widely used in military and civilian applications. In the 3mm band, since power amplifiers and other MMIC (monolithic microwave integrated circuit) devices are still in the exploratory research stage, their output power is at the level of several hundred milliwatts, which limits the development of the 3mm band system. [0003] With the development of military electronic technology, the demand for the output power of 3mm wave solid-state transmitters is getting higher and higher, but the output power of MMIC-based microwave c...
