Description

technical field

[0001] The invention relates to the technical field of PCB connection, in particular to a radio frequency PCB connection structure and a connection method. Background technique

[0002] With the rapid development of mobile communication, especially the development of 4G communication, there are more and more demands for product serialization and platformization. In serialized products, modularizing circuits with the same function will effectively reduce the development cycle and reduce the cost. This design concept is also applicable to radio frequency circuits. The use of sub-board design for radio frequency circuits will be more conducive to reducing costs, obtaining better performance, and serialization and platformization. However, how to connect two RF PCBs (Printed Circuit Boards, printed circuit boards) to achieve good RF impedance control and lower cost is the key to serialization, modularization and platformization of RF circuits.
