Product Summary
The AD8312ACBZ-P7 is a complete, low cost subsystem for the measurement of RF signals in the frequency range of 50 MHz to 3.5 GHz. It has a typical dynamic range of 45 dB and is intended for use in a wide variety of cellular handsets and other wireless devices. The AD8312ACBZ-P7 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. Applications are (1)Cellular handsets (GSM, CDMA, WCDMA); (2)RSSI and TSSI for wireless terminal devices; (3)Transmitter power measurement.
