Description
Key features include dual logarithmic amplifiers followed by precision phase detectors, enabling it to provide a DC output proportional to the log of the magnitude ratio (in dB) and another DC output proportional to the phase difference (in degrees). This makes it useful for RF power measurement, RSSI, and vector voltmeter applications.
The device operates with a single 5V supply and boasts a low power consumption of around 100 mW. It comes in a compact 14-lead TSSOP package, making it suitable for space-constrained designs.
The AD8302ARUZ’s ability to simultaneously measure gain and phase makes it an ideal choice for applications like antenna return loss measurement, RF/IF signal chain characterization, and quadrature demodulation systems.
