摘要： A Radio Frequency (RF) transceiver includes a first RF transceiver group, a second RF transceiver group, local oscillation circuitry, and calibration control circuitry. Each of the RF transceiver group has an RF transmitter and an RF receiver. The local oscillation circuitry selectively produces a local oscillation to the first RF transceiver group and to the second RF transceiver group. The calibration control circuitry is operable to initiate calibration operations including transmitter self calibration operations, first loopback calibration operations, and second loopback calibration operations. During loopback calibration operations, test signals produced by an RF transceiver group are looped back to an RF receiver of another RF transceiver group.

摘要： A communications transceiver includes a baseband processor, a receiver section, and a transmitter section that includes a power amplifier. The receiver and transmitter sections communicatively couple to the baseband processor. In a calibration operation, the baseband processor produces a test signal to the transmitter section. Further, the baseband processor causes each of a plurality of power amplifier bias settings to be applied to the power amplifier. For each of the plurality of power amplifier bias settings, the power amplifier produces an amplified test signal, the receiver section couples back a portion of the amplified test signal to the baseband processor, and the baseband processor produces a characterization of the amplified test signal respective. Based upon a plurality of characterizations of the amplified test signal and respective power amplifier bias settings, the baseband processor determines power amplifier bias control settings. The baseband processor then applies the power amplifier bias control settings to the power amplifier.

摘要： Often programmable gain attenuators (PGAs) are combined with high pass filters. Adjustment of the highpass filter however can have unintended effects, such as changing the step size of the PGA. By placing the resistance of the highpass filter in parallel with a programmable attenuator divider, the steps of the PGA can be minimally affected as the highpass frequency is adjusted.

摘要： A power amplifier includes a transconductance stage and a modulation detection and bias determination module, and may include a cascode stage. The modulation detection and bias determination module operably couples to the transconductance stage and to the cascode stage when present and is operable to detect modulation characteristics of an signal operated upon by the transconductance stage. The modulation detection and bias determination module is also operable to controllably bias the transconductance stage and/or the cascode stage when present based upon detected modulation characteristics. The detected modulation characteristics are typically determined based upon a measured signal level, e.g., voltage level, current level, or power level, of the signal operated upon by the transconductance device. For non-constant envelope modulations, the signal level varies over time with the modulation envelope. The operational characteristics of the power amplifier, e.g., biasing condition(s), are therefore varied over time with the variation of the modulation.
