Classification: CPC H | IPC H

Claim 13:
14. A method, comprising:
determining reference data indicative of characteristics for each of two or more amplifiers of a radio apparatus, wherein the amplifiers are configured for amplifying respective signals in respective different frequency bands, the reference data including voltage characteristics required by a particular amplifier to achieve each of a range of output power values for its respective frequency band while meeting one or more predetermined performance requirements, wherein the voltage characteristics comprise a drain voltage and a gate bias voltage required for the particular amplifier to achieve a particular output power for its respective radio frequency band,
wherein the method comprises determining the voltage characteristics in a testing stage when the two or more amplifiers and/or signal processing components associated with the two or more amplifiers are configured to meet the one or more predetermined performance requirements, and
wherein the one or more predetermined performance requirements comprise one or more of maintain group delay variation and an out-of-band rejection.
