Problems solved by technology

If the installation process is wrong, the performance of the MMIC chip will not be fully utilized, and the chip will be damaged if it is serious.

Foreign countries have always been in the leading position in the manufacture, installation and use of MMIC chips, but they are in a state of technical secrecy in terms of millimeter-wave micro-assembly technology, and there is no complete information to consult and learn from.
