AD606 INPUT LEVEL CONVENTIONS RF logarithmic amplifiers usually have their input specified in “dBm,” meaning “decibels with respect to 1 mW.” Unfortu- nately, this is not precise for several reasons. 1. Log amps respond not to power but to voltage. ...

V The slope is essentially independent of temperature. The intercept P is essentially independent of either the supply X voltage or temperature. However, the AD606 is not factory calibrated, and both ...

AD606 Offset-Control Loop The offset-control loop nulls the input offset voltage, and sets up the bias voltages at the input pins INHI and INLO. A full understanding of this offset-control loop is useful, particularly when using larger input coupling capacitors ...

For operation above 10 MHz not necessary to add the external capacitors CF1, CF2, and C , although an improve- Z ment in low frequency noise can be achieved by so doing (see APPLICATIONS). Note that the offset ...

AD606 Adjustment Procedure The slope and intercept adjustments interact; this can be mini- mized by reducing the resistance of R1 and R2, chosen here to minimize power drain. Calibration can be achieved in several ways: The simplest is to apply ...
