Note 1: Differential IFI and IFQ output impedance without the use of a 9:1 impedance ratio balun.
Note 2: The recommended LO input power level can vary from –3 dBm to +3 dBm for the 900, 1900, and 2600 MHz RF input frequencies. Above 3300 MHz, better performance is achieved by
using a higher LO input power level such as +5 dBm.
Note 3 : When a +5 dBm LO input power level is applied at 3600 MHz, the typical IIP2 value is 51 dBm and the typical IIP3 value is 22.5 dBm.
