Abstract :
A novel power control concept has been applied to a monolithic integrated power amplifier for the PCS/PCN frequency range of 1.9 to 2.4 GHz. At 3.3 V supply voltage the amplifier has a saturated power of 22.7 dBm at 1.95 GHz, which can be decreased continuously or in steps by an on chip control transistor. The amplifier has an efficiency better than 25% at P/sub sat/ and a gain of 25 dB at P/sub -1/ /sub dB/.
