Note 1:
The MAX2014 is guaranteed by design for T
A
= -40°C to +85°C, as specified.
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 stated bounds. The error is calculated at T
A
= -40°C
and +85°C, relative to the curve at T
A
= +25°C.
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
(RMS) straight line to the data indicated by 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 calculated by fitting an RMS straight line to the data.
