Two-tone IIP3. Tested at f RF1 = 880MHz, f RF2 = 880.9MHz, and power = -25dBm/tone.
Two-tone IIP3. Tested at f RF1 = 1960MHz, f RF2 = 1961.25MHz, and power = -25dBm/tone.
F LO = 1064MHZ, f RF1 = 887.8MHz at -30dBm, f RF2 = 881MHz at -100dBm. Performance is measured as P IF due to
RF1 - P IF due to RF2.
Note 7: F LO = 2143MHz, f RF1 = 2051.5MHz at -35dBm, f RF2 = 1960MHz at -100dBm. Performance is measured as P IF due to
RF1 - P IF due to RF2.
