Abstract: A modularly-partitioned feedforward multicarrier linear RF power amplifier i s described. The circuitry and components of the power amplifier are segregated into physically-separate modules in accordance with several criteria. In one embodiment, the power amplifier is segregated into a RF power module, a linearizer module and a DC power supply module. The RF power module includes power- and frequency- dependent components and general ly varies with the carrier frequency and output power requirements for a specific application. The linearizer module includes circuitry and components that are substantially power- and frequency- independent. As such, the linearizer module is substantially invariant and a single design may be used for virtually any application. The DC power supply module includes circuit and components that are substantially frequency independent but somewhat power dependent. T he DC power supply module may vary from amplifier to amplifier where there is a significant change in output power requirements.
