Abstract: A transmission line coupler (115) for a transmitter output signal (123) generated by an RF signal amplifier (103) includes a through-path transmission line (201) and a coupled-path transmission line (202) electromagnetically coupled thereto by multiple serpentine-like portions (such as portions 641, 642, 643 and 644 in Fig. 6), which are disposed on opposite sides of the through-path transmission line (201) for enhancing coupling sensitivity and eliminating degradation in the amount of coupling due to variations in the transmission line plating registration. Offset portions (641, 643) on one side of the through-path transmission line (201) provide substantially the same amount of coupling as the offset portions (642, 643) on the other side of the through-path transmission line (201). The transmission line coupler (115) is embedded in the output match of the final amplifier (103) and includes complex impedances (212 and 210, 222) at each port of the coupled-path transmission line (202) for substantially eliminating undesired reflections. The coupled port of the coupled-path transmission line (202) is coupled by an inductor (211) to a hot-carrier diode (206) for enhancing the detection sensitivity thereof.

Abstract: 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.

Abstract: A power amplifier load adjust system includes a power amplifier and a variable impedance network coupled to the output of the power amplifier. The variable impedance network presents a plurality of impedances to the output of the power amplifier responsive to a load control signal. A control circuit generates a transmit power command and a channel frequency command. Memory stores a plurality of control values as a function of output power and frequency. A processing circuit coupled to the variable impedance network, the control circuit, and the memory retrieves the plurality of control values and uses them to generate the load control signal in response to the transmit power command and the channel frequency command.

Abstract: A method (800) and an apparatus for controlling power associated with a transmitting unit (220). The transmitting unit (220) may generally include a processing component (310), a baseband controller (320), a linearization controller (330), a variable baseband source (340), and a radio frequency (RF) component (350). The variable baseband source (340) may generate a baseband signal based on an input signal. The RF component (350) may generate an RF signal based on the baseband signal. The processing component (310) may generate a first control signal and a second control signal. Further, the processing component (310) may provide the first control signal to the baseband controller (320) to adjust the variable baseband source (340), and provide the second control signal to the linearization controller (330) to adjust the RF frequency component (350).

Abstract: An amplifier is disclosed, suitable for a mobile transmitter, which is capable of supplying power to a load at a plurality of different power levels, and with increased efficiency at low power levels. The bias applied to the power amplifier at low power output differs from that applied at high power. In addition, the output of the amplifier is loaded with a different impedance at low power output, than at high power output. Thus, in comparison with prior art, it is possible at low power output to reduce the bias further, increasing efficiency, while the amount of noise or power transmitted in an adjacent channel remains acceptable. In an embodiment, the power amplifier changes between high and low power outputs at a different threshold level depending upon whether the amplifier is transition from a higher to a lower power output, or from a lower to a higher.

Abstract: A power amplifying circuit with load adjust for control of adjacent and alternate channel power. A power amplifier amplifies an input signal to produce an amplified signal. A variable impedance network presents different impedances to the output of the power amplifier responsive to a load control signal. A peak-to-average detector provides an indication of a peak-to-average ratio of the amplified signal. A controller coupled to the peak-to-average detector and the variable impedance network produces the load control signal responsive to the indication of the peak-to-average ratio.
