DUPLEXER WITH ENHANCED ISOLATION |
摘要 |
A system includes a transmit filter (160) in a transmit path to couple to an antenna (120) and pass signals in a transmit band. A receive filter (155) is disposed in a receive path to couple to the antenna and to the transmit filter to pass signals in a receive band different from the transmit band. An enhanced frequency variable impedance (145) is used to provide isolation between signals in the transmit and receive bands on the receive path. A phase and magnitude controlled feedback path can also be used to cancel transmit signals in the receive path. |
