Figure 44. LO Output Power
Measurements are done at 25 degree C unless temperature is specified in the plots.
For measurements across LO frequency, IF = 65MHz, and LO injection type is high side injection. For measurements across IF frequency, high side injection is applied
For all measurements that require RF input, RF input power = -10 dBm unless otherwise specified.
For two-tone measurements, the separation between two tones is 17MHz.
For all measurements, internal 1.7V VCM is applied.
For all external LO mode measurements, LO power = +6 dBm.
IF baluns used for measurements are: ADT2-18+ from Mini-Circuits™.
LO balun used for measurements is: BIB-100G from PPM-Test™.
RF combiner used for measurements of IP2, IP3 and NF with jammer is: 4426-2 from Narda-MITEQ™.
All path losses are calibrated out.
