Frequency conversion plans
All 6700/6900 series BUCs are frequency inverting, that is,
the higher the RF frequency required, the lower the modem
IF frequency must be.
To calculate the modem IF frequency (f
IF
) for a given
RF frequency, subtract the RF frequency (f
RF
) from the LO
frequency (f
LO
).
