摘要： A system includes a plurality of band pass filters to pass signals in separated frequency bands to or from an antenna. A matching network provides characteristic impedances. The system is designed such that the configuration of the matching network and BPFs provides high impedance to the band pass filters for those routing paths other than the band pass path as these routing paths do not transmit or receive the signals at this particular pass band. The system is further designed such that the configuration of the matching network and BPFs provides minimal insertion loss for the band pass path of for transmission and receipt of signals at this particular pass band, where each routing path has a corresponding pass band. The matching network is for coupling to an amplifier, when frequency separation is needed at the output of the amplifier to the BPFs. In one embodiment an impedance network tunes the impedance by using varying length transmission lines.

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.

摘要： A serial controller is adapted to receive an external clock and an input data, and output an inverted clock and an output data. The serial controller includes an inverter, a serial position detector, a synchronous clock generator, a serial register, and a half-cycle delay unit. Thereby, through the serial controller, the problem that the data signal and the driving clock are not synchronous when the clock series are inverted is avoided. Besides, a bi-directional serial controller further includes an identification unit and a data directing unit, and the serial controller is enabled to return the current status to a central control unit to serve as the reference for error detection.
