摘要:
The complete active portion of the 3G UMTS/WCDMA cellular handset RF sub-system is achieved with three RFICs. This chipset comprises a fully integrated ZIF Receiver including RF VCO/PLL and UMTS clock generation, a fully integrated direct conversion like Transmitter including RF VCO/PLL, and a 25dBm average Power Amplifier including power detection circuitry. The three RFICs use the same baseline 0.25um BiCMOS technology opening possibilities to even higher integration level. This chipset is targeted at handset class 3 and 4 (PA is class 4 compatible only) European and Japanese 3G UNITS and WCDMA standards.
