2.5GHz 45dB RF-Detecting Controllers

_______________________________________________________________________________________

Note 1: All devices are 100% production tested at TA = +25°C and are guaranteed by design for TA = -40°C to +85°C as specified.

All production AC testing is done at 100MHz.

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 gm stage, responds to

a voltage step at the SET pin (see Figure 1).

Note 4: Typical min/max range for detector.

Note 5: MAX4000 internally AC-coupled.

Note 6: MAX4001/MAX4002 are internally resistive-coupled to VCC.

ELECTRICAL CHARACTERISTICS

(VCC = 3V, SHDN = 1.8V, fRF = 100MHz to 2.5GHz, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)
