Abstract: Controllable radio frequency power amplifiers (RFPAs), e.g., in a Hybrid-MIMO array, which are being driven at lower power levels, are operated at conditions such that their inherent EVM and ACLR are intentionally further increased. This increase of inherent EVM and ACLR is done in a precise manner, and the increased inherent EVM and ACLR are cancelled or reduced by the EVM and ACLR of the input Array DPD signal. The net result is improved EVM and ACLR performance over a broader range of angles. Exemplary methods and apparatus for increasing distortion include individual or combinations of: i) changing the DC bias a RFPA based on average operating power level; ii) changing supply voltage, e.g. Vcc, of a RFPA based on average operating power level, iii) adding a controllable non-linear element, such as a diode or varactor, at the input of the RFPA, based on the average operating power.
