The RF2488 is a dual-band LNA/Mixer designed to sup-
port dual-band, multi-mode handset applications. The
unique dual IF outputs provide interface to two indepen-
dent 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 inde-
pendent IF bandwidths accessible from either the low or
high band LNAs. Each LNA has a gain bypass mode con-
trolled by the GAIN SEL pin. An image reject filter is
required between each LNA and its mixer. Power man-
agement is implemented based on a three-pin logic level
interface. Power consumption is minimized by shutting
down all but the active sections of the device.
