Abstract
A radar transceiver is provided. The radar transceiver includes an electrical balance duplexer that is coupled to a transmission node of a transmission path, a reception node of a reception path, and an antenna node and that is configured to isolate the transmission path from the reception path. The electrical balance duplexer includes a hybrid transformer network and a non-tunable balancing impedance. The non-tunable balancing impedance is configured to provide a fixed impedance value that corresponds to an impedance value at the antenna node.
Claims20
A radar transceiver comprising:
- an electrical balance duplexer coupled to a transmission node of a transmission path, a reception node of a reception path, and an antenna node, wherein the electrical balance duplexer is configured to isolate the transmission path from the reception path, wherein the electrical balance duplexer comprises a hybrid transformer network and a non-tunable balancing impedance, and wherein the non-tunable balancing impedance is configured to provide a fixed impedance value that is defined corresponding to an impedance value at the antenna node.
A method for antenna sharing in a radar transceiver, the method comprising:
- Operating an electrical balance duplexer to isolate a transmission path from a reception path, wherein the electrical balance duplexer comprises a hybrid transformer network and a non-tunable balancing impedance, wherein the electrical balance duplexer is coupled to a transmission node of the transmission path, to a reception node of the reception path, and to an antenna node, and wherein the non-tunable balancing impedance is configured to provide a fixed impedance value that is defined corresponding to an impedance value at the antenna node.
