Notes
1. Adjust input voltage Vis to 0 dBm level (0 dBm = 1 mW into 600 Ω).
2. Adjust input voltage Vis to 0 dBm level at Vos for 1 MHz (0 dBm = 1 mW into 50 Ω).
Vis is the input voltage at an nYn or nZ terminal, whichever is assigned as an input.
Vos is the output voltage at an nYn or nZ terminal, whichever is assigned as an output.
Test conditions:
VCC = 4.5 V; GND = 0 V; VEE = −4.5 V;
RL = 50 Ω; Rsource = 1 kΩ.
