A 3.3 V front-end receiver GaAs MMIC for the digital/analog dual-mode hand-held phones
A front-end receiver MMIC for 3.3 V-operating CDMA/AMPS dual-mode hand held phone has been developed using a GaAs MESFET process. The developed MMIC, chip size of which is 1.9/spl times/3.9 mm/sup 2/ shows noise figure of 2.8 dB, power gain of 35/25 dB at the nominal current consumption of 22.5/16.1 mA in CDMA/AMPS modes, respectively.
