*) Type means: A = 100% tested, B = 100% correlation tested, C = Characterized on samples, D = Design parameter
Notes: 1. The required LO level is a function of the LO frequency.
2. In reference to an RF output level ≤ –1 dBm and I/Q input level of 400 mV_pp differential.
3. Sideband suppression is tested without connection at pins 15 and 16. For higher requirements a potentiometer can be
connected at these pins.
4. For T_amb = –30°C to +85°C and V_S = 4.5V to 5.5V.
5. By low impedance signal source.
