ADL5507ACBZ

ADL5507ACBZ is a complete, low-power, wide-band logarithmic RF power detector for the measurement of RF signals in the 10MHz to 12GHz frequency range. This device is optimized for accurate RF signal level measurements over a 55dB dynamic range, from -56dBm to -1dBm at 3.6GHz, when terminated with 50 ohm. It provides a wider dynamic range and better accuracy than is possible using discrete diode detectors. Its high sensitivity allows the measurement of low power levels, thus reducing the amount of power that needs to be coupled to the detector. The output interface has sufficient capability to drive a wide range of analogue‐to‐digital converters (ADCs) and other circuitry. It is used in applications such as RSSI and TSSI for wired and wireless terminal devices, RF transmitter or receiver power measurement, and wide-band automatic gain control.
