AD8367:  500 MHz, 45 dB Linear-in-dB Variable Gain Amplifier

Product Details


Silicon Bipolar VGA with integrated Square Law Detector

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.

The AD8367 is fabricated on a high performance silicon bipolar process, package in 14-lead thin shrunk small outline (TSSOP) package fully specified over –40°C to +85°C temperature range.
