Copyright (c) 2005-2007, Texas Instruments Incorporated TRF2436 www.ti.com SLWS176C - APRIL 2005 - REVISED MAY 2007 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. DESCRIPTION The TRF2436 is a fully integrated Dual Band Tri Mode Radio Frequency Front End (RFFE) designed specifically for use in 802.16 d/e applications. The TRF2436 is designed to perform RF up and down conversions in the unlicensed ISM and 4.9-5.9 GHz bands. The TRF2436 uses a common IF frequency for both bands, eliminating the need for additional IF filtering. Combined with the TI TRF2432 IF/IQ Transceiver/Synthesizer, the TRF2436 completes the TI WLAN two-chip radio. The TRF2436 incorporates all of the RF blocks for both the "b" and "a" bands except for low cost ceramic filters. The ASIC includes LNAs, PAs, mixers, bias circuitry, RX gain control, transmit coupler detectors, and T/R switches. High integration and internal RF matching enhances performance and greatly reduce external part count. The only external components needed (other than simple passives) for operation are RF filters and external low power DC switching FETs.
