Configurable wireless communication device with configurable front-end

摘要

A configurable wireless communication device includes a baseband processing module, a transmitter section, a receiver section, an antenna, transmit/receive isolation circuits, high frequency switches, and a configuration module. The baseband processing module converts outbound data into an outbound symbol stream and converts an inbound symbol stream into inbound data. The transmitter section converts the outbound symbol stream into an outbound signal and the receiver section converts an inbound signal into the inbound symbol stream. The configuration module, in a power combining mode, couples, via a set of high frequency switches, the antenna to a set of transmit/receive isolation circuits, wherein a number of the transmit/receive isolation circuits in the set of transmit/receive isolation circuits is based on a desired combined transmit power.
