描述 Description

GENERAL DESCRIPTION
The CGY2021G is a DCS/PCS class 1 GaAs Monolithic Microwave Integrated Circuit (MMIC) power amplifier specifically designed to operate at 4.8 V battery supply.
The chip also includes a power sensor driver so that no directional coupler is required in the power control loop.FEATURES
? Power Amplifier (PA) overall efficiency 50% (DCS)
? 34 dB gain
? 0 dBm input power
? Gain control range 50 dB
? Integrated power sensor driver
? Low output noise floor of PA ? Wide operating temperature range?20 to +85°C
? LQFP 48-pin package
? Compatible with power ramping controller PCA5077 and GaAs PA power modulator UBA1710.APPLICATIONS
? Hand-held transceivers for DCS/PCS applications (DCS: 1710 to 1785 MHz and PCS: 1850 to 1910 MHz)
? 1800 MHz Time Division Multiple Access (TDMA) systems.
