Datasheet Analog Devices AD8314ARMZ-REEL

100 MHz to 2.7 GHz, 45 dB
RF Detector/Controller
AD8314 Data Sheet
FEATURES For convenience, the signal is internally ac-coupled, using a
5 pF capacitor to a load of 3 kΩ in shunt with 2 pF. This highpass coupling, with a corner at approximately 16 MHz,
determines the lowest operating frequency. Therefore, the
source can be dc grounded. Complete RF detector/controller function
Typical range:−58 dBV to −13 dBV
−45 dBm to 0 dBm, re 50 Ω
Frequency response from 100 MHz to 2.7 GHz
Temperature-stable linear-in-dB response
Accurate to 2.7 GHz
Rapid response: 70 ns to a 10 dB step
Low power: 12 mW at 2.7 V
Power down to 20 µA The AD8314 provides two voltage outputs. The first, V_UP,
increases from close to ground to about 1.2 V as the input signal
level increases from 1.25 mV to 224 mV. This output is intended
for use in measurement mode. Consult the Applications section
for information on this mode. A capacitor can be connected
between the V_UP and FLTR pins when it is desirable to
increase the time interval over which averaging of the input
waveform occurs. APPLICATIONS
