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: According to the method and apparatus of the present disclosure, dual drain control uses a variable voltage supply on the drains of a first stage (302) and a second stage (304) to control the output power. In particular, dual drain control having a 1:1 ratio is employed at lower power levels, with single drain control at higher power levels. Such drain control could be employed by directly varying (1008, 1010) the voltage on the drains of the power amplifier, such as with signals from a microprocessor, or by a specific circuit (203) to generate the drain voltages based upon a control voltage.

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.

Abstract: A transmitter (107) includes amplifying circuitry (203) and control circuitry (215, 217, 219) for biasing the amplifying circuitry (203) so that it operates closer to saturation with increased efficiency. The gate voltage signal (213), which provides a gate bias, is coupled to the amplifying circuitry (203) and is dynamically varied by the processor circuitry (219) in response to the value of the amplifier control voltage (211) coupled to the amplifying circuitry (203). The amplifier control voltage (211), which has a value for maintaining the output power of the amplifying circuitry (203) at a constant, is produced by the integrating circuitry (217) in response to a comparison of the detected power output signal (216) produced by the detecting circuitry (215) and the power output control signal (218) produced by the processor circuitry (219). Efficiency is realized by dynamically varying the gate voltage signal (213) to its largest magnitude so that the amplifying circuitry (203) may operate as close to saturation as possible while still maintaining a constant output power.
