The AD8309ARUZ-REEL7 is a logarithmic amplifiers manufactured by Analog Devices, and it is specifically designed to offer linear-in-dB repeater gain control. With a wide frequency range of 5-500 MHz, it provides excellent 100 dB gain accuracy, low distortion, and flat gain response over the entire range. It also features a Limiter Output pin, which allows the user to easily detect signal overloads and prevent saturation of the output signal. This part is available in a 7-inch reel and is RoHS compliant. This chip is suitable for a wide range of RF applications such as satellite receivers, cable TV amplifiers, RF radio systems, and microwave transceivers.
