Microstrip coupler combining transmit-receive signal separation and differential to single ended conversion
Sprache des Patenttitels:
Englisch
Original Kurzfassung:
One embodiment relates to a coupler that can be
used in a radar system. The coupler includes differential ports, an
antenna port, a receiver port, a local port and a transmission path. The
differential ports are configured to receive a differential signal. The
antenna port is configured to output a transmitted signal and to input a
received signal. The transmitted signal is derived from the differential
signal. The receiver port is configured to output a portion or version
of the received signal. The local port outputs a local signal, which is
also derived from the differential signal. The transmission path is
coupled to the differential ports, the antenna port, the receiver port
and the local port. The transmission path typically has a length
selected to derive or output the signals at the above ports.
