MAX9930–MAX9933
2MHz to 1.6GHz 45dB RF-Detecting
Controllers and RF Detector
_______________________________________________________________________________________ 3
Note 1: All devices are 100% production tested at T
A
= +25°C and are guaranteed by design for T
A
= -40°C to +85°C as specified.
Note 2: Typical value only, set-point input voltage range determined by logarithmic slope and logarithmic intercept.
Note 3: Set-point slew rate is the rate at which the reference level voltage, applied to the inverting input of the g
m
stage, responds to
a voltage step at the SET pin (see Figure 1).
Note 4: Typical min/max range for detector.
Note 5: Pin capacitance to ground.
