AD8313ARM

The AD8313ARM is a complete RF/IF RMS power detector with a 45 dB dynamic range in a compact 8-lead MSOP package. It operates over a frequency range of 50 MHz to 3.5 GHz and provides a fast response time of 10 ns for detecting rapidly changing signals. The device offers a wide power detection range from -65 dBm to 0 dBm, making it suitable for a variety of applications in communication systems, radar systems, and power control circuits.The AD8313ARM features a temperature-stable, proprietary logarithmic amplifier design that ensures accurate power measurement over a wide temperature range. It also has a low power consumption of 6.5 mA at 3V supply voltage, making it suitable for portable and battery-powered applications.The device provides a single-ended linear DC output voltage that can be interfaced with a microcontroller or ADC for further processing. It also has built-in temperature compensation and an enable pin for power-saving mode.
