LOW-LOSS ELECTRICAL BALANCE DUPLEXER WITH NOISE CANCELLATION |
| 摘要 |
A circuit for a low-loss duplexer with noise cancellation in a receive (RX) path of a transceiver includes a duplexer, a balancing network, and a noise cancellation circuit. The duplexer circuit is coupled to an antenna of the transceiver. The balancing network is coupled to the duplexer and provides an impedance matching an impedance associated with the antenna. The noise cancellation circuit senses a noise signal generated by the balancing network and uses the sensed noise signal to improve a signal-to-noise ratio (SNR) of the RX path. |

1. A circuit for a low-loss duplexer with noise cancellation in a receive (RX) path of a transceiver, the circuit comprising:
a duplexer circuit coupled to an antenna of the transceiver; a balancing network coupled to the duplexer and configured to provide an impedance matching an impedance associated with the antenna; and a noise cancellation circuit configured to sense a noise signal generated by the balancing network, and to use the sensed noise signal to improve a signal-to-noise ratio (SNR) of the RX path. |
