A 6–9GHz WiMedia UWB RF transmitter in 90nm CMOS

A 6-9 GHz RF transmitter fabricated in a standard digital 90 nm CMOS technology and targeted for WiMedia UWB bandgroup 3 and 6 is presented. The transmitter features high linearity, low spurious emission, low power and small chip area. Measured data show - 5.7dBm output power, -1.4- dBm OIP3, -47 dBc LO leakage and -33.8 dBc sideband rejection with only 72 mW from a 1.2 V power supply at a minimal chip area of 0.24 mm 2 active area.
