APPLICATIONS 1800 MHz transceiver for DECT hand-portable equipment TDMA systems. GENERAL DESCRIPTION The UAA2067G is a low-power transceiver intended for use in portable and base station transceivers complying with the DECT system. The IC performs in accordance with specifications in the −30 to +85°C temperature range. The UAA2067G contains a front-end receiver for the 1800 to 1900 MHz frequency range, a high-frequency VCO for the 1650 to 1850 MHz range, a low-frequency VCO for the 100 to 140 MHz frequency range and a transmitter with a high-output power amplifier driver stage for the 1800 to 1900 MHz frequency range. 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 a...
