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 <−121 dBm/Hz in DCS/PCS RX band

• 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.
