The AD8367S from Analog Devices is a variable-gain amplifier with an automatic gain control detector designed to be used at IF frequencies up to 500 MHz. It has an accurate gain control with a 45 dB span and a 3 dB bandwidth of 500 MHz. The amplifier has a noise figure of 4.7 dB and a P1dB of 14.4 dBm. It has an in-built 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. The amplifier has a power dissipation of 200 mV and is radiation tested for 100 Krads. It 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. This MIL-STD-1835 amplifier is fabricated on a high-performance silicon bipolar process packaged in a 14-lead thin-shrunk small outline.
