Abstract
An IF strip for a wireless receiver supports a variable baud rate by changi ng analog filter bandwidth. Sliding and step adaptive dynamic range are bot h used at EF to dissipate only the necessary power at prevailing channel co nditions. A combination of VGA and PGA is developed for 64-QAM. The total s ignal processor draws an average of 16 mA from 3.3 V and a peak of 73 mA. T he differential input noise is as low as 3.9nV/root Hz, while maximum IIIP3 is +22 dBm with respect to 100 ohms.
