RF2488

The RF2488 is a dual-band LNA/Mixer designed to supportdual-band, multi-mode handset applications. Theunique dual IF outputs provide interface to two independentIF SAW filters supporting applications that combineIS136 with GSM, DCS or EDGE air interfaces. The deviceincludes four mixers, providing the ability to use two independentIF bandwidths accessible from either the low orhigh band LNAs. Each LNA has a gain bypass mode controlledby the GAIN SEL pin. An image reject filter isrequired between each LNA and its mixer. Power managementis implemented based on a three-pin logic levelinterface. Power consumption is minimized by shutting own all but the active sections of the device.
