Note 1: The MAX2016 is tested at T
A
= +25°C and is guaranteed by design for T
A
= -40°C to +85°C.
Note 2: Typical minimum and maximum range of the detector at the stated frequency.
Note 3: Dynamic range refers to the range over which the error remains within the ±3dB range.
Note 4: The slope is the variation of the output voltage per change in input power. It is calculated by fitting a root-mean-square
straight line to the data indicated by the RF input power range.
Note 5: The intercept is an extrapolated value that corresponds to the output power for which the output voltage is zero. It is calcu-
lated by fitting a root-mean-square straight line to the data.
