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.

Tools & Simulations


Sys-Parameter Models for Keysight Genesys

Sys-Parameter models contain behavioral parameters, such as P1dB, IP3, gain, noise figure and return loss, which describe nonlinear and linear characteristics of a device.


Design Tools


ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.


ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
