Linear Technology 

LTC5540

AC Electrical Characteristics VCC = 3.3V, VCCIF = 3.3V, SHDN = Low, TA = 25°C, PLO = 0dBm,

PRF = –3dBm (∆f = 2MHz for two-tone IIP3 tests),unless otherwise noted. Test circuit shown in Figure 1. (Notes 2, 3, 4)

High-Side LO Downmixer Application: RF = 600MHz to 1100MHz, IF = 190MHz, fLO = fRF+fIF
