Embodiment 1

[0024] The invention proposes a new multi-channel signal adapter with adjustable phase. It looks like figure 2 As shown, the signal adapter uses an air coaxial cable as a microwave signal transmission line, and the port connected to the outside is a jack structure, which can realize blind mating interconnection; it uses a dielectric screw made of high dielectric constant material for adjustment The phase of the transmission line for each channel. Adjusting the phase adjustment screw, on the one hand, can ensure the phase consistency of the air coaxial line of each channel, on the other hand, it can also be adjusted according to the phase characteristics of the external channel module, so that the phase consistency of the entire channel is in a good state.

[0025] The multi-channel signal adapter of the present invention includes an upper cover plate 2, a lower cover plate 1 and an adapter 3 with the same N-way structure connecting the upper cover plate and the lower cover p...

Embodiment 2

[0036] On the basis of Embodiment 1, a square groove is opened at the end where the circular through hole of the upper cover plate is connected to the rectangular groove, and a square groove is also opened at the position corresponding to the circular through hole of the upper cover plate and the lower cover plate, and the square grooves are filled with The square supporting medium 8, 9, and the circular through hole of the upper cover plate and the circular through hole of the lower cover plate are filled with circular supporting medium 6, 7 at the same time.

[0037] The square support medium is in the shape of a cube, and is provided with an arc-shaped 90° turning through hole 13, the turning through hole can realize that the inner conductor enters from one side of the square support medium and exits from the other side, (the two sides of the entrance and exit are not parallel), And play a role in fixing the bending angle of the inner conductor.

[0038] A through hole 12 i...

Abstract

The present invention provides a multi-channel signal adapter, comprising: an upper cover, a lower cover and an N-channel adapter; each channel of the adapter includes a phase modulation screw, an inner conductor, a supporting medium, an upper cover Both the upper cover and the lower cover have circular through holes, and the lower cover also has a rectangular groove; the upper cover and the lower cover are fixed so that the upper cover has a circular through hole, the lower cover has a rectangular groove, and the lower cover The circular through holes are connected in turn to form a zigzag passage, and the inner conductor passes through the zigzag passage to form an air coaxial line. The support block provides necessary support for the inner conductor in the air coaxial line; the two ends of the inner conductor are respectively placed on the upper cover plate The circular through hole and the end of the circular through hole of the lower cover are respectively provided with elastic openings, and the upper cover is also provided with at least one threaded through hole to the rectangular slot, and the phase adjustment screw passes through the threaded through hole to air at the same time. The electrical length of the axis is adjusted. The multi-channel signal adapter of the present invention can realize blind-mating interconnection, has good phase consistency, and is small in size and easy to install.

Description

technical field [0001] The invention relates to the field of microwave communication, in particular to a multi-channel signal adapter. Background technique [0002] In a microwave communication system, especially in a multi-channel microwave communication system, multiple microwave signals need to be transmitted from one functional module to another with a certain amplitude and phase relationship. For the case where the positions of the channel ports of the two modules are exactly the same, the best interconnection method is through blind insertion, and two-to-two docking; and for the case where the port positions of the channel modules are inconsistent, the interconnection can only be realized through high-frequency cable assemblies. [0003] The existing method for achieving consistent transmission of multi-channel signals is to use high-frequency cable assemblies that meet certain requirements for amplitude consistency and phase consistency, and connect the functional mod...
