Front-end module comprising an EBD circuit, telecommunication device comprising the front-end module and method for operating them. Interuniversitair Micro-Electronica Centrum vzw
The present disclosure relates to a front-end module for a telecommunication device with an EBD circuit (1) comprising a hybrid transformer (2) for coupling via a transmit port (21) to the telecommunication device transmitting a first frequency transmit signal, to an antenna (4), via a receive port (23) to the telecommunication device receiving a second frequency receive signal, and to a tuneable impedance circuit (6). In a first configuration the EBD circuit (1) is configured to isolate the transmit port (21) from the receive port (23) at the first frequency, and the FEM comprises a first ...
