DESCRIPTION
The RX/TX circuit provides the down conversion to the data stream and the up conversion from the first IF. In conjunction with TEMIC’s RF front end, Twin PLL, I/Q modulator and AMDs CT2 PhoXTM controller AM 79C4xx a complete CT2 IC kit is available. Electrostatic sensitive device. Observe precautions for handling. FEATURES
D Low supply voltage 2.9 V typical (min. 2.7 V) D Provides down conversion to the data stream, D D D D D D D up conversion from the first IF Integrated UHF and VHF VCOs Low noise figure of RX path (NF 10 dB) RX and TX power down First IF filter used for transmit as well receive mode Temperature compensated logarithmic Receiver Signal Strength Indicator (RSSI) with a 75 dB dynamic range Low power consumption in RX and TX mode (<20 mA typ.)
