RF2488 - MULTI-MODE DUAL-BAND LNA MIXER

Description

The RF2488 is a dual-band LNA/Mixer designed to support dual-band, multi-mode handset applications.

The unique dual IF outputs provide interface to two independent IF SAW filters supporting applications that combine IS136 with GSM, DCS or EDGE air interfaces.

Features

  • Complete Dual-Band Front-End.
  • Switchable LNA Gain.

Preliminary RF2488 MULTI-MODE DUAL-BAND LNA MIXER 8 Typical Applications • TDMA/EDGE Handsets • TDMA IS-136 Handsets • GAIT Handsets • TDMA/GSM Dual-Band Handsets • GSM/DCS/EDGE Handsets Product Description The RF2488 is a dual-band LNA/Mixer designed to support dual-band, multi-mode handset applications. The unique dual IF outputs provide interface to two independent IF SAW filters supporting applications that combine IS136 with GSM, DCS or EDGE air interfaces. The device includes four mixers, providing the ability to use two independent IF bandwidths accessible from either the low or high band LNAs. Each LNA has a gain bypass mode controlled by the GAIN SEL pin. An image reject filter is required between each LNA and its mixer.
