AD8309ARUZ-REEL7

AD8309 is a complete IF limiting amplifier, providing both an accurate logarithmic (decibel) measure of the input signal (the RSSI function) over a dynamic range of 100dB, and a programmable limiter output, useful from 5MHz to 500sMHz. It is easy to use, requiring few external components. Typical application includes receivers for frequency and phase modulation, very wide range IF and RF power measurement, receiver signal strength indication(RSSI), Low cost radar and sonar signal processing and instrumentation: network and spectrum analysers.
