Abstract
A multi-band RF transmitter circuit () for a wireless communication device combines a plurality of RF transmission blocks into a single transceiver integrated circuit which includes a shared broadband SVGA (), a shared tunable balun (), and an output switching network () at the output of the balun to support three different frequency bands. The outputs of the multi-band RF transmitter circuit are connected to separate external power amplifier circuits (-), where each power amplifier circuit generates an amplified signal for one of the plurality of predetermined frequency bands.
