5兆赫， 400兆赫百分贝高精度限流，对数放大器 5 MHz-400 MHz 100 dB High Precision Limiting-Logarithmic Amplifier

Product Details

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.

An evaluation board is available for this product and may be ordered using the following product number: AD8306-EVAL. Schematic and layout for this evaluation board is contained in the product datasheet.
