Abstract

See full text

A converged device with dual RFPA technology for a dynamic switchable mode. One example provides a communication device comprising a RF transmitter system and a controller. The RF transmitter system includes a plurality of RFPAs, each RFPA having a biasing system and outputting an output signal, and a summing junction, wherein the output signal of each RFPA are combined to form an output RF transmitter signal. The controller is configured to control the biasing state of each biasing system to a nominal bias state for a first mode of the communication device. The controller is configured to control a first plurality of offset voltages applied to each biasing system for a second mode of the communication device. The controller is configured to control a second plurality of offset voltages applied to each biasing system for a third mode of the communication device.
