The following figure illustrates a detailed block diagram of the Yoda RX chip.

In this dual-mode transmitter, the BB I and Q signal input buffer, modulator, IF VGA, up-

converter, RF VGA, and the PA driver will be integrated on a single IC called Jedi. This Tx

IC, Jedi, includes VHF synthesizers with external tanks and the UHF PLL circuitry exclud-

ing VCOs. This Tx IC plus Cell and PCS band power amplifiers, SAW filters, power detec-

tors, isolators, and duplexers form the transmitter. Therefore, it is a highly integrated

transmitter.
