TDA8263HN
Fully integrated satellite tuner
Unwanted signal: RF1 is 1040 MHz and PRFIN = −20 dBm and RF2 is 1100 MHz and PRFIN = −20 dBm. The output level of (RF1 + RF2)
on the output pins is P2.

[dBm], see Figure 5
Wanted signal: RF1 is LO + 5 MHz, PRFIN = −20 dBm and the AGC adjusted to get 550 mV (p-p) on the differential output.
Unwanted signal: RF1 is LO + 5 MHz and PRFIN = −23 dBm, RF2 is LO + 7 MHz and Pin = −23 dBm.
