Problems solved by technology

[0003] However, in actual use, the castle board will jump due to the pad size, force, board material and trace width of the master board, resulting in impedance jumps at the connection between the master and daughter boards, which will lead to RF quality such as insertion loss and Reflection and other indicators become worse, greatly affecting the quality of signal transmission

Abstract

The invention discloses a manufacturing method of a base station radio frequency circuit based on a PCB castle board. The radio frequency circuit includes a digital intermediate frequency board and a plurality of power amplifier boards. The method includes: covering a first pad with a patch for the digital intermediate frequency board; The board covers the second pad with via holes, wherein the microstrip line between the top device of the power amplifier board and the second pad is a direct arc line; connect the first pad of the digital intermediate frequency board to the power amplifier The butt joints of the second pads of the board are aligned and attached; the joints are heated to realize the RF circuit welding of the PCB castle board. According to the method disclosed in the present invention, the pain points and difficulties existing in the existing castle solution of the 5G base station can be solved, and rigid requirements such as large coverage area, large bandwidth, high capacity, and low delay of the base station can be met.

Description

technical field [0001] The invention relates to the technical field of PCB castle boards, in particular to a manufacturing method of a base station radio frequency circuit based on the PCB castle boards. Background technique [0002] With the large-scale application of 5G networks, rigid requirements such as large coverage, wide bandwidth, high capacity, and low latency are put forward for base stations. The construction of base station equipment is characterized by larger bandwidth, higher frequency band, and higher power. Single-chip Transceiver integrates multi-channel transceivers, that is, each base station equipment needs multiple antennas to achieve 2T2R, 4T4R or more, and requires high signal transmission quality. These aspects greatly increase the complexity of the circuit design of the internal printed board of the base station equipment, especially It is the radio frequency hardware circuit, and the design level of the radio frequency hardware circuit determines t...
