DESCRIPTION
The TRF2432 is a fully integrated IQ transceiver specifically for use in 802.16 d/e applications. The TRF2432 is
designed to perform the IQ conversion at 374MHz IF as well as provide an RFLO and control logic to a TI RFFE
(Radio Frequency Front End). The TRF2432 uses a common IF frequency for both bands, which eliminates the
need for an additional IF filter in dual band applications. The TRF2432 has an internal IQ DC offset calibration
function for the receive IQ interface. Combined with a TI integrated RFFE, the TRF2432 completes the TI WLAN
two-chip radio.

TRF2432
SLWS177B–APRIL 2005–REVISED NOVEMBER 2006
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.
The TRF2432 incorporates all of the system blocks from the modem to the RFFE except for the IF filtering and
the reference crystal. The ASIC uniquely incorporates an internal PLL reference oscillator where only a crystal is
needed, and also provides a clock output for base-band/MAC ASICs. TRF2432 includes two synthesizers with
VCOs, IQ modulator, IQ demodulator, anti aliasing filters, IF amplifiers, receive AGC circuit, transmit power
control and serial interface.
