Embodiment Construction

[0033] 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 and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0034] It should be noted that when an element is referred to as being “disposed on” or “fixed on” another element, it may be directly on another element or there may be an intervening element. When an element is referred to as being "fixed on" another element, or "fixedly connected" to another element, it may be detachably fixed or non-detachably fixed therebetween. When an element is referred to as being "connected" or "rotatably connected" to another element, it can be directly connected to the other element or intervening elements may also be pres...

Abstract

The invention discloses a radio frequency device and a conversion device between a coaxial port and a waveguide port. The conversion device between a coaxial port and a waveguide port includes a conversion body and a conversion component. The conversion body is provided with a conversion channel, and one end of the conversion channel There is a first opening for communicating with the waveguide port, the side wall at the other end of the conversion channel is provided with a first resonant column with a coaxial port, the conversion component is arranged in the conversion channel, and the conversion component is set Between the first opening and the first resonant column and connected to the first resonant column, the conversion component is used to enable energy coupling between the waveguide port and the coaxial port. The conversion device between the coaxial port and the waveguide port can reliably switch the coaxial port and the waveguide port while ensuring the coupling bandwidth; in this way, the radio frequency device using the conversion device between the coaxial port and the waveguide port can realize very wide coupling bandwidth.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a radio frequency device and a conversion device between a coaxial port and a waveguide port. Background technique [0002] With the rapid development of 5G technology, antennas are also developing towards higher frequencies. Since the frequency bands of 5G technology (3400MHz-3600MHz and 4800MHz-4900MHz) will interfere with the C-band of satellite communication earth stations (the specific frequency band is 3700MHz-4200MHz). In order to eliminate this interference, the traditional method is to add a filter to suppress the 5G frequency band on the satellite communication earth station. Since the filter adopts the coaxial port structure, and the signal transmission of the satellite communication earth station adopts the waveguide port structure, it is impossible to reliably convert the coaxial port and the waveguide port under the condition of ensuring the coupling b...
