Abstract: 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.

Abstract: A device, system and method for transmitting one or more of annotations and video prior to a video call is provided. A communication device receives a request for a video call from a first communication device, of other communication devices. Prior to the video call being established, the communication device: determines whether a user of the first communication device is an authorized caller; and when the user of the first communication device is an authorized caller, transmits, to the first communication device, one or more of annotations received at the input device and video from a video camera. The determination of whether a user of the first communication device is an authorized caller is based on profile data associated with users of one or more of the other communication devices.
