Isolation optimization technique for 5G RF cavity

Electromagnetic cavity shielding in RF circuit design is a vital part of electromagnetic compatibility and signal integrity. For 4G frequencies this is relatively easy to achieve as the cavity size tends to be small compared to the wavelength. In 5G technology, where carrier frequencies are in very high frequencies (e.g. ...
