Product Overview

The AD8309ARUZ 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 5 to 500MHz. It is easy to use, requiring few external components. A single supply voltage of +2.7 to +6.5V at 16mA is needed, corresponding to a power consumption of under 50mW at 3V, plus the limiter bias current, determined by the application and typically 2mA, providing a limiter gain of 100dB when using 200W loads. A CMOS-compatible control interface can enable the AD8309 within about 500ns and disable it to a standby current of under 1mA. The programmable output stage provides a further 18dB of gain. The input is fully differential and presents a moderately high impedance (1kΩ in parallel with 2.5pF). The input-referred noise-spectral-density, when driven from a terminated 50Ω.
  • Complete multistage log-limiting IF amplifier
  • Programmable limiter gain and output current
ESD sensitive device, electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.
