描述 Description

GENERAL DESCRIPTION
The UAA2077TS contains a 2 GHz front-end receiver intended to be used in mobile telephones. Designed in an advanced BiCMOS process it combines high performance with a low power consumption and high integration, thus reducing external component costs and overall front-end size.FEATURES
? Low noise, wide dynamic range amplifier
? Very low noise figure
? Dual balanced mixers for over 30 dB on-chip image rejection
? Quadrature 200 MHz IF recombiner
? On-chip quadrature network
? Independent SX, RX, power-down control modes and fast power-up switching
? Very small outline packaging
? No image filter required, resulting in a very small application.APPLICATIONS
? GSM dual band solution with UAA3522HL
? High frequency front-end for DCS1800/PCS1900 portable hand-held equipment
? Compact mobile digital communication equipment
? Time Division Multiple Access (TDMA) receivers e.g.
? RF Local Area Networks (RF LANs).
