Problems solved by technology

With the development of millimeter-wave circuits, the frequency band of radio frequency signals is continuously expanding to high frequencies, and the wavelength is constantly shortening. The precision of the traditional microstrip line and waveguide conversion form in the process of processing and installation can no longer meet the performance design requirements. In order to achieve The waveguide-microstrip conversion function, this design provides a structure that can perform waveguide-microstrip vertical conversion in the submillimeter wave band

Embodiment Construction

[0023] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0024] The waveguide microstrip vertical conversion structure of the present invention is based on the principle of microstrip transmission line and waveguide electromagnetic wave theory. The strip line is then connected across the waveguide, and the other end is crimped on the chip capacitor, and the other end of the chip capacitor is grounded through the ground hole. This structure completes the conversion of TEM mode on the microstrip line to the TE10 mode of the rectangular waveguide, and realizes the function of waveguide microstrip conversion.

[0025] In this waveguide microstrip vertical conversion structure, the 50Ω microstrip line used to transmit radio frequency signals uses silica quartz material as the dielectric substrate, which has higher processing accuracy than the traditional microstrip line dielectric substrate. For the continuity of RF signal...

Abstract

The invention relates to a waveguide-microstrip conversion structure in a terminating capacitor arc probe form, and belongs to the technical field of radio frequency circuits. An arc-shaped probe structure is realized through a gold strip crimping process, one end of a gold strip is crimped on a microstrip line and then is bridged in a waveguide, the other end of the gold strip is crimped on a chip capacitor, and the conversion between a microstrip TEM mode and a waveguide TE10 mode is realized in an electric field coupling mode. The waveguide-microstrip conversion structure does not need microstrip linear conversion, is good in performance and simple in structure, and can be applied to a sub-millimeter wave band radio frequency signal transmission circuit.

Description

technical field [0001] The invention belongs to the technical field of radio frequency circuits, and designs a waveguide-microstrip conversion structure in the form of a terminal capacitor arc probe based on the characteristics of submillimeter wave band circuits and according to the principle of microstrip transmission lines and waveguide electromagnetic wave theory. One end of the external port in this conversion structure is a 50-ohm microstrip line, and the other port is a standard BJ2600 waveguide port. Background technique [0002] The main transmission structures of millimeter-wave radio frequency signals include microstrip lines, waveguides, and coaxial lines. Among them, the microstrip line adopts the form of a planar circuit, which has the advantages of flexible and diverse forms, easy installation, and convenient circuit debugging. It is mainly used in circuits such as frequency mixing, frequency multiplication, amplification, and filtering of radio frequency sign...
