摘要： An apparatus includes a transmit-receive switch circuit and a detector circuit. The transmit-receive switch circuit may be connected between an input port, an output port, and a common port, and configured to switch a transmit radio-frequency signal from the input port to the common port in a transmit mode and a receive radio-frequency signal from the common port to the output port in a receive mode. The detector circuit may be integrated within the transmit-receive switch and may be configured to generate a power detection signal in response to at least one of the transmit radio-frequency signal or the receive radio-frequency signal.

摘要： An apparatus includes a transceiver circuit, a series capacitor, and a shunt switch. The transceiver circuit may comprise a transmit chain including an output matching network and a receive chain including an input matching network. An output of the output matching network may be connected directly to an input/output of the transceiver circuit. The series capacitor may be connected between an input of the input matching network and the output of the output matching network. The shunt switch may be connected between the input of the input matching network and a circuit ground potential of the transceiver circuit.

摘要： An apparatus includes an impedance matching network, a first switch circuit, and a second switch circuit. The impedance matching network generally comprises a first port, a second port, and a third port. The first switch circuit may be coupled between the first port and a circuit ground potential. The second switch circuit may be coupled between the second port and the circuit ground potential. The impedance matching network generally provides a first impedance value for the first port and for the third port when the second port is connected to the circuit ground potential. The impedance matching network generally provides a second impedance value for the second port and for the third port when the first port is connected to the circuit ground potential. The first impedance value and the second impedance value are asymmetrical.

摘要： An apparatus includes a plurality of conductive layers and a plurality of traces configured to carry a plurality of signals through a change of direction. The traces may be routed parallel to each other in a first trace segment in a first of the conductive layers toward the change of direction. The traces may be routed parallel to each other in a second trace segment in a second of the conductive layers in the change of direction. One of the traces in a third trace segment in the first conductive layer may cross over another of the traces in the second trace segment in the second conductive layer in the change of direction. The traces may be routed parallel to each other in the third trace segment in the first conductive layer away from the change of direction.
