Rectifier input,

V2 = +6dBm, V1 = 0dB

V2 = -30dBm, V1 = 0dB

NOTES:

1. Input to V1 and V2 grounded.

2. Measured at 0dBm, 1kHz.

3. Expandor AC input change from no signal to 0dBm.

4. Relative to value at TA = 25°C.

5. Electrical characteristics for the SA571 only are specified over -40 to +85°C temperature range.

6. 0dBm = 775mVRMS.
