    摘要: An integral phase shifting network of a transmitter filter provides a means to reduce the size and increase the efficiency of an antenna coupling network. The network to shift the phase of the transmitter filter is printed by depositing conductive material directly on a ceramic block using low-loss circuit elements and can be tuned easily by removing conductive material if required in certain applications. By utilizing an integral phase shifting network, either transmit or receive filters having a higly reactive and capacitive out-of-band impedance in the receive or transmit band, respectively, can be connected to a common antenna port without external transmission lines.

    摘要: A method and apparatus mitigates spurious transmissions. An offset local oscillator signal is generated that is at a frequency that is offset from a nominal transmit channel carrier frequency by a spurious mitigation offset. An information signal is generated that comprises a series of modulation symbols and has a transmission bandwidth at baseband. A configured offset information signal is generated from the information signal, wherein the spectrum of the configured offset information signal is offset from DC by a channel configuration offset, and is further offset by a negative of the spurious mitigation offset. The offset local oscillator signal and the configured offset information signal are combined using a mixing technique. The spurious mitigation offset is zero when a spurious condition does not exist and is non-zero when the spurious condition does exist.

    摘要: A transmitter circuit (10) includes a phase shifter (20) that receives phase shift compensation and timing data (40), and an amplifier (30) that receives a control signal (70) to initiate an efficiency enhancement technique. The phase shifter (20) receives the phase shift compensation and timing data (40), and the amplifier (30) receives the control signal (70) at a pre-defined relative time such that the compensation phase shift by the phase shifter (20) compensates for a pre-determined phase change in the amplifier (30) to produce an RF output signal (80) with a reduced predicted phase change.
