UAA2077BM

INTEGRATED CIRCUITS DATA SHEET UAA2077BM 2 GHz image rejecting front-end Product specification Supersedes data of July 1995 File under Integrated Circuits, IC03 1995 Dec 13 Philips Semiconductors Product specification 2 GHz image rejecting front-end FEATURES Low-noise, wide dynamic range amplifier Very low noise figure Dual balanced mixer for over 25 dB on-chip image rejection IF I/Q combiner at 188 MHz On-chip quadrature network Down-conversion mixer for closed-loop transmitters Independent TX/RX fast ON/OFF power-down modes Very small outline packaging Very small application (no image filter). APPLICATIONS 1800 MHz front-end for DCS1800 hand-portable equipment Compact digital mobile communication equipment TDMA receivers e.g. PCS and RF-LANS. GENERAL DESCRIPTION UAA2077BM contains both a receiver front-end and a high frequency transmit mixer intended to be used in mobile telephones. Designed in an advanced BiCMOS process it combines high performance with low power consumption and a high degree of integration, thus reducing external component costs and total front-end size. The main advantage of the UAA2077BM is its ability to provide over 25 dB of image rejection. Consequently, the image filter between the LNA and the mixer is suppressed.
