Measured in the evaluation board (see Chapter 4), worst case in band
2).
This is the level of divider interferences close to the IF frequency. For example channel S3:
fOSC = 158.15 MHz, 1/4 fOSC = 39.5375 MHz. Measured in the evaluation
board (see Chapter 4).
3).
Channel S02 beat is the interfering product of fRF, fIF and fOSC of channel S02, fbeat = 37.35 MHz.
The possible mechanisms are fOSC - 2 x fIF or 2 x fRFpix - fOSC. Measured in evaluation board
