UAA2077TS

INTEGRATED CIRCUITS DATA SHEET UAA2077TS 2 GHz image rejecting front-end Preliminary specification Supersedes data of 2000 Mar 09 File under Integrated Circuits, IC17 2000 Apr 17 Philips Semiconductors Preliminary specification 2 GHz image rejecting front-end 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). 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.
