PRODUCT DESCRIPTION

The AD8306 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 100 dB, and a programmable limiter output, useful from 5 MHz to 400 MHz.

It is easy to use, requiring few external components. A single supply voltage of +2.7 V to +6.5 V at 16 mA is needed, corresponding to a power consumption of under 50 mW at 3 V, plus the limiter bias current, determined by the application and typically 2 mA, providing a limiter gain of 90 dB when using 200 ? loads. A CMOS-compatible control interface can enable the AD8306 within about 500 ns and disable it to a standby current of under 1 μA.

The six cascaded amplifier/limiter cells in the main path have a small signal gain of 12.04 dB (×4), with a –3 dB bandwidth of 850 MHz, providing a total gain of 72 dB. The programmable output stage provides a further 18 dB of gain. The input is fully differential and presents a moderately high impedance (1 k? in parallel with 2.5 pF). The input-referred noise-spectral-density, when driven from a terminated 50 ?, source is 1.28 nV/√Hz, equivalent to a noise figure of 3 dB. The sensitivity of the AD8306 can be raised by using an input matching network.

Each of the main gain cells includes a full-wave detector. An additional four detectors, driven by a broadband attenuator, are used to extend the top end of the dynamic range by over 48 dB.
