Abstract: A multi-band, multi-standard programmable power amplifier having tunable impedance matching input and output networks and programmable device characteristics. The impedance of either or both of the impedance matching input and output networks is tunable responsive to one or more control signals. In one example, the programmable power amplifier incorporates a feedback control loop and the control signal(s) are varied responsive to the feedback loop.

Abstract: A fully integrated, programmable mixed-signal transceiver comprising a radio frequency integrated circuit (RFIC) which is frequency and protocol agnostic with digital inputs and outputs, the transceiver being programmable and configurable for multiple radio frequency bands and standards and being capable of connecting to many networks and service providers. The RFIC does not use spiral inductors and instead includes transmission line inductors allowing for improved scalability. Components of the transceiver are programmable to allow the transceiver to switch between different frequency bands of operating. Frequency switching can be accomplished though the content of digital registers coupled to the components.
