Highly-integrated SiGe BiCMOS WCDMA transmitter IC

A highly-integrated SiGe BiCMOS WCDMA transmitter IC consists of VHF, UHF chains, and synthesizers. At 6 dBm output power, it consumes 79 mA at 2.7 V, with a 5% r.m.s. EVM and -42 dBc ACLR at 5 MHz offset. In-band and receive-band output noise are -128 and -135 Bm/Hz, respectively. Fully integrated PLLs use on-chip VCO tanks and require no off-chip loop filters.
