    摘要: A method in a wireless communication transmitter including a baseband processor (310) that dynamically configures the transmitter for a particular signal configuration, and a headroom controller (350) for adjusting transmitter headroom based on the particular signal configuration. In one embodiment, the PA headroom is controlled based on a power metric, for example, a 3rd order polynomial or peak to average ratio (PAR) metric, that is a function of the signal configuration. In another embodiment the PA headroom is adjusted using information in a look up table.

    摘要: A radio frequency (RF) coupler apparatus (312) suited for use in a multi-band wireless communication device (200), has a termination device (316) and couplers (314 and 315). Each of the couplers (314 and 315) has through-path coupling elements (318 and 320) and coupled-path coupling elements (319 and 321). Through-path coupling elements (318 and 320) pass a RF signal that is to be transmitted respective frequency bands (TX BAND 1, TX BAND 2) within which the device (200) operates. Coupled-path coupling elements (319 and 321) couple the RF signals passed by respective through-path coupling elements (318 and 320). The coupled-path coupling elements (319 and 321) and the termination device (316) are coupled in series, thereby permitting compatibilty with a RF power detector (313) that uses a single detection diode (322).

    摘要: A polar modulation power amplifier circuit includes a control circuit (101) to determine and provide a load selection signal (127), wherein the load selection signal (127) is determined responsive to a requested power signal (119). A power amplifier (113) is responsive to a power control signal (141), for amplifying an RF signal (139) to produce an amplified signal (145), having an output power level. A variable impedance matching circuit (117) is responsive to the load selection signal (127), to adjust a relationship between the control level and the output power level, to produce a range-adjusted amplified signal (147).
