Popis: A 3-stage 21 to 26GHz SiGe PA with 21dBm output power is presented. Small-signal gain is approximately 20dB and reverse isolation is 12.5%. On-chip transformers are extensively used to efficiently couple common-base stages and I/O to source and load, respectively. The 2.45/spl times/2.45mm/sup 2/ chip is fabricated in a 0.18/spl mu/m SiGe BiCMOS process (f/sub T/=100GHz) and draws 450mA from a 1.8V supply.
