آی سی RF دیتکتور AD8314 دارای پکیج MSOP8

Description:
The AD8314 is a complete low cost subsystem for the measurement and control of RF signals in the frequency range of 100 MHz to 2.7 GHz, with a typical dynamic range of 45 dB, intended for use in a wide variety of cellular handsets and other wireless devices.
It provides a wider dynamic range and better accuracy than possible using discrete diode detectors.
In particular, its temperature stability is excellent over the full operating range of −40°C to +85°C.
Its high sensitivity allows control at low power levels, thus reducing the amount of power that needs to be coupled to the detector.

It is essentially a voltage-responding device, with a typical signal range of 1.25 mV to 224 mV rms or –58 dBV to −13 dBV. This is equivalent to −45 dBm to 0 dBm, re 50 Ω.

Cellular handsets (TDMA, CDMA , GSM)
RSSI and TSSI for wireless terminal devices
Transmitter power measurement and control
