Abstract:
1. A method, comprising: configuring a single programmable output stage of a multi-band, multi-standard transmitter to handle transmission of a signal according to a selected one of a plurality of wireless communication protocols and a corresponding one of a plurality of frequency ranges associated with said signal, wherein said single programmable output stage comprises switched impedance matching circuits at inputs of a differential pair and a plurality of switched load elements at outputs of said differential pair; biasing a power amplifier within said single programmable output stage to operate in one of a plurality of classes of operation associated with said selected one of said plurality of wireless communication protocols; configuring said single programmable output stage for said selected one of a plurality of wireless communication protocols by selectively coupling said power amplifier within said single programmable output stage to at least one of a switch or a duplexer; and selectively coupling said at least one of a switch or a duplexer to one of a plurality of antennas.
