    Abstract: 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.

    Abstract: A method of offsetting a mismatch due user interaction when handling a portable wireless terminal in which antenna matching is changed from inductive matching to capacitive matching in response to a reactance change exceeding a threshold level and vice versa when an opposite change is detected. An antenna interface module (44) is coupled between a RF output or input stage (25 or 33) and an antenna (48 or 50). The antenna interface module includes first and second switches (SW1/1, SW1/2 or SW2/1, SW2/2), a first matching circuit including an inductive reactance (68 or 96) coupled between the power amplifier and the first switch and a second matching circuit including a capacitive reactance (68 or 92) is coupled between the RF output or input stage and the second switch (SW1/1 or SW2/1 ). A reactance threshold detector (54 or 56) determines if the reactance change traverses a predetermined threshold value and causes the first and second switches to be actuated so that the matching changes from inductive to capacitive or vice versa.

    Abstract: A multiplexer, such as a diplexer, is delineated. The multiplexer may be employed in a communications system that may communicate in multiple frequency bands within a predefined range of frequencies, e.g., 2400 MHz - 4900 MHz. The communications system may operate in a network, such as a wireless local area network, without significant interference from signals used by a cellular/mobile telephone system. The multiplexer may include multiple channels with bandpass filters that may be formed with lumped inductors and lumped capacitors. In at least one of the channels, the bandpass filter may be formed by combining at least one lowpass filter with at least one highpass filter.
