Abstract
Circuitry, which includes multi-mode multi-band radio frequency (RF) power amplification circuitry, power amplifier (PA) control circuitry, and a PA-digital communications interface (DCI) is disclosed according to one embodiment of the circuitry. The PA control circuitry is coupled between the amplification circuitry and the PA-DCI, which is coupled to a digital communications bus, and configures the amplification circuitry. The amplification circuitry includes at least a first RF input and multiple RF outputs, such that at least some of the RF outputs are associated with multiple communications modes and at least some of the RF outputs are associated with multiple frequency bands. Configuration of the amplification circuitry associates one RF input with one RF output, and is correlated with configuration information defined by at least a first defined parameter set. The PA control circuitry stores at least a first look-up table (LUT), which provides the configuration information.
