DEVICE INFORMATION

TRF2436

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 foamduring storage or handling to prevent electrostatic damage to the MOS gates.

The TRF2436 is a fully integrated Dual Band Tri Mode Radio Frequency Front End (RFFE) designed specificallyfor use in 802.16 d/e applications. The TRF2436 is designed to perform RF up and down conversions in theunlicensed ISM and 4.9-5.9 GHz bands. The TRF2436 uses a common IF frequency for both bands, eliminatingthe need for additional IF filtering. Combined with the TI TRF2432 IF/IQ Transceiver/Synthesizer, the TRF2436completes 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/Rswitches. High integration and internal RF matching enhances performance and greatly reduce external partcount. The only external components needed (other than simple passives) for operation are RF filters andexternal low power DC switching FETs.

TBD: The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements

for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered

at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and

package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS

compatible) as defined above.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame

retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
