Abstract :
Configured as a two-step architecture, the circuit generates the first up-converted signal in quadrature phases and subsequently performs single-sideband modulation to produce the output in the two bands. Fabricated in a 0.6-/spl mu/m CMOS technology, the transmitter draws 70 mW from a 3-V supply.
