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.

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.
