Overview
The ADL5902ACPZ-R7, produced by Analog Devices Inc., is a true rms responding power detector designed for high-frequency signal measurement. It operates over a wide frequency range of 50 MHz to 9 GHz and features a 65 dB measurement range when driven with a single-ended 50 Ω source. This versatility eliminates the need for external input tuning, making it suitable for various high-frequency systems. The device is powered by a single 5 V supply and requires only a few capacitors for operation, making it easy to integrate into different designs.
