AD8367S:  Aerospace 500 MHz, 45 dB Linear-in-dB Variable Gain Amplifier

Product Details

Product Status:Recommended for New Designs

The AD8367 is a high-performance variable gain amplifier designed to be used at IF frequencies up to 500 MHz. An externally applied analog gain control voltage of 0 to 1 volt, scales the 45 dB of gain control range to provide 20 mV/dB output. The precise linear-dB gain control is achieved with a proprietary X-AMP™ architecture, consisting of a variable attenuator network fed by a Gaussian interpolator yielding precise linear gain adjustment.

In addition the AD8367 has an integrated square law detector, which enables the part to be used as an AGC solution and provides a detected received signal strength indication (RSSI) output voltage.

The AD8367 has been specified for operation at common IF frequencies 70 MHz, 140 MHz, 190 MHz and 240 MHz found in the cellular CDMA / GSM and W-CDMA applications.


  • Wide bandwidth 500 MHz (-3 dB bandwidth)
  • Linear-in-dB continuous analog gain control
  • Integrated on chip square law detector for AGC operation
  • High linearity output IP3 36.5 dBm @ 70 MHz
