[1] The product is qualified with an output voltage of 550 mV (p-p) differential, however larger values can be used at baseband outputs that
might have impact on the product performance.
[2] IIP₂ = −20 + (P1 − P2) [dBm].
Wanted signal: RF1 is 2140 MHz, P_RFIN = −20 dBm, and the AGC adjusted to get 550 mV (p-p) on the differential output. The output
level is P1.
Unwanted signal: RF1 is 1040 MHz and P_RFIN = −20 dBm and RF2 is 1100 MHz and P_RFIN = −20 dBm. The output level of (RF1 + RF2)
on the output pins is P2.
[3] IIP₃ = −23 + -^I--^M-₂----³-- [dBm], see Figure 6
Wanted signal: RF1 is LO + 5 MHz, P_RFIN = −20 dBm, and the AGC adjusted to get 550 mV (p-p) on the differential output.
Unwanted signal: RF1 is LO + 5 MHz and P_RFIN = −23 dBm and RF2 is LO + 7 MHz and Pin = −23 dBm
[4] Phase noise in optimal conditions, see related application note.
