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. Multiple gain control options are provided to achieve a very large dynamic range for the receiver. A frequency doubler is included in the LO circuit to generate both high- and low-band LO signals with a single VCO. The RF2492 is packaged in a 32 pin, 5mmx5mm, leadless plastic package.
