The 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 100 dB, and a programmable limiter output, useful from 5 MHz to 500 MHz.
It is easy to use, requiring few external components. A single supply voltage of +2.7 V to +6.5 V at 16 mA is needed, corre- sponding to a power consumption of under 50 mW at 3 V, plus the limiter bias current, determined by the application and typically 2 mA, providing a limiter gain of 100 dB when using 200 Ω loads. A CMOS-compatible control interface can enable the AD8309 within about 500 ns and disable it to a standby
current of under 1 µA.
