RF Micro Devices RF2488
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.| Part No. | RF2488 |

DESCRIPTION
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. Power management 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. .80 .65 1.00 0.85 4.00 sq. .60 typ .24 .45 .20 4 PLCS 2.25 sq. 1.95 12° max .05 .01 .55 .30 2 .40 .28 .50 .23 .13 4 PLCS Optimum Technology Matching® Applied Si BJT Si Bi-CMOS Package Style: LCC, 24-Pin, 4x4 üSiGe HBT VCC BIAS Low LNA OUT Low LNA VCC 24 23 22 GaAs HBT GaAs MESFET Si CMOSFEATURES
