ADAPTIVE LOAD FOR COUPLER IN BROADBAND MULTIMODE MULTI-BAND FRONT END MODULE |
摘要 |
Directional couplers for front end modules (FEMs) are disclosed that include a first port configured to receive a radio-frequency (RF) signal, a second port connected to the first port via a first transmission line and configured to provide an RF output signal, and a third port connected to a second transmission line, the second transmission line coupled to the first transmission line. A directional coupler in accordance with the present disclosure may further include a termination circuit connected to the second transmission line and configured to provide a first impedance when the RF signal is within a first frequency band and provide a second impedance when the RF signal is within a second frequency band. |
