WIDEBAND COUPLER FOR IMPROVING PIMD PERFORMANCE

摘要

Disclosed is a wideband coupler for increasing PIMD performance. According to an embodiment of the present invention, the wideband coupler implements a wideband diplexer using a low pass filter and a high pass filter and proposes a suspended structure to lift a PCB substrate in the air, capable of minimizing a tunneling effect which is a main cause of contact nonlinear PIMD for increasing the PIMD performance.;COPYRIGHT KIPO 2018
