FC1703

Future Communications Integrated circuit Inc. FC1703 Receiver RFIC for Dual-Band Triple Mode DESCRIPTION The FC1703 is designed primarily for use in a receiver front-end of the dual-band, triple- mode system, operating in the Advanced Mobile Phone System (AMPS), Cellular Code-Division Multiple-Access (CDMA), and PCS CDMA. The IC contains low-noise amplifiers (LNA), and mixers with a balanced IF outputs. The unit operates at 2.7V single power and is designed to use with RF SAW filter. It is possible to adjust current level, gain, and IIP3 by changing resistors. The IC is manufactured on a SiGe BiCMOS process, and is packaged in a leadless small package, named MLF-24 FEATURES l Complete Receiver Front-end of the dual-band Cellular/PCS Mobile-phone System, (AMPS and CDMA) l Integrated LNA, and Down-converting mixers l Triple-mode of LNA l Low Single voltage operation (2.7V) l High Linearity l Low power consumption l Adjustable IIP3, Gain and Current l 4mm x 4mm Small leadless package PIN CONFIGURATION PLNA_OUT PMIX_IN APPLICATIONS AMPS-mode Cellular mobile phone.
