Abstract
An upconverter and two driver amplifiers for CDMA/AMPS cellular/PCS wireless transmitters are presented. The upconverter has two selectable RF outputs operating over 800 to 1900 MHz frequency range. They can be assigned to different frequency bands providing a dual-band operation. The driver amplifiers offer two gain modes selected with a control voltage. The cellular driver amplifier provides DC power savings in the low gain mode. The chip set was fabricated using a GaAs 0.6 /spl mu/m E/D MESFET process.Keywords
