Preliminary 8 Typical Applications • TDMA-GSM Cellular/PCS Handsets • TDMA Cellular/PCS Handsets • GAIT Handsets RF2492 DUAL-BAND LOW NOISE AMPLIFIER/MIXER • CDMA Cellular/PCS Handsets • GSM DCS/PCS Handsets Product Description The RF2492 is a fully featured dual-band LNA/Mixer and is usable in a variety of mobile handset applications. The unique dual IF outputs provide interface to two independent IF SAW filters supporting applications such as TDMA-EDGE where 30kHz and 200kHz bandwidth SAW filters are used. With independent power management control pins for the LNAs and mixers, either IF output can be accessed from either high- or low-band LNAs, providing maximum flexibility with minimum power usage.
