AD8312ACBZ-P7 GENERAL DESCRIPTION

The AD8312 is a complete, low cost subsystem for themeasurement of radio frequency (RF) signals in the frequencyrange of 50 MHz to 3.5 GHz. It has a typical dynamic range of45 dB and is intended for use in a wide variety of cellular handsetsand other wireless devices. It provides a wider dynamic rangeand better accuracy than possible using discrete diode detectors. Inparticular, its temperature stability is excellent over the fulloperating range of −40°C to +85°C. Its high sensitivity allowsmeasurement at low power levels, thus reducing the amount ofpower that needs to be coupled to the detector. It is essentially avoltage responding device, with a typical signal range of 1.25 mVto 224 mV rms or −45 dBm to 0 dBm, referencing 50 Ω.For convenience, the signal is internally ac-coupled, using a5 pF capacitor to a load of 3 kΩ in shunt with 1.3 pF. This high-pass coupling, with a corner at approximately 16 MHz, determinesthe lowest operating frequency. Therefore, the source may be dcgrounded.The AD8312 output, VOUT, increases from close to ground toabout 1.2 V because the input signal level increases from 1.25 mVto 224 mV. A capacitor may be connected between the VOUTand CFLT pins when it is desirable to increase the time intervalover which averaging of the input waveform occurs.The AD8312 is available in a 6-ball, 1.0 mm × 1.5 mm, waferlevel chip scale package and consumes 4.2 mA from a 2.7 V to5.5 V supply.
