摘要：RF polar modulation circuit has a self-compensated temperature stableenvelope controller and self-compensated temperature stable power amplifier bias. Thecircuit has an adaptive current-to-voltage modulation interface with pre-distortion
compensation capability. AM/PM distortion are compensated for envelope dependentpower amplifier transistor biasing. Automatic compensation is provided for RF loads thatare higher or lower than nominal loads. This Abstract is provided to comply with rulesrequiring an Abstract that allows a searcher or other reader to quickly ascertain subjectmatter of the technical disclosure. This Abstract is submitted with the understanding thatit will not be used to interpret or limit the scope or meaning of the claims.
