RFFE POWER CONTROL INTERFACE
The TRF2432 will control the RFFE power for all radio operational modes through three external P-MOSFETs.
The suggested circuit is illustrated in Figure 4.

IQ DC Calibration
The TRF2432 receiver has an IQ DC offset calibration function. This operation can be performed in receiver
active mode only. The calibration process is entered by a rising edge on CALEN, which remains high as long as
the calibration is required. The calibration procedure is as follows:
1. Set to RX active mode
2. Wait for RF and IF Synthesizers to lock: STATUS=HIGH
3. Set Rx AGC to min gain
4. Set CALEN=HIGH to enter calibration mode:
a.
IQ Transceiver turns off RFFE
b.
Internal calibration process runs

The IF frequency synthesizer defaults to integer mode (FN_IF =0) to operate from a 44 MHz reference and is
preset for 374 MHz IF. When using a 40 MHz reference, the synthesizer must be set to fractional mode (FN_IF
=1) and programmed. The synthesizer is programmed with four bytes DI, SI, FI and MI. The register
programming values for the IF synthesizer when using a 40 MHz reference are listed in Table 21.
