RF Power Detector
Product Introduction
RF Power Detector is developed to meet the demand for realtime, accurate, and reliable RF power measurement in highfrequency transmission and test scenarios. Traditional power measurement solutions often suffer from large size, narrow frequency coverage, and slow response speed—issues that RF Power Detector overcomes through its integrated circuit design and advanced semiconductor materials. It supports frequency bands from 100kHz to 67GHz and offers measurement ranges from 60dBm to +30dBm, covering lowpower signal monitoring and highpower signal detection. The component is constructed with highstability semiconductor materials and features optional digital interfaces for easy data transmission, making it suitable for both commercial consumer electronics and harsh industrial/defense applications.

FAQ
Q: What is the difference between active and passive RF Power Detector?
A: Passive RF Power Detector converts RF power into electrical signals without external power, featuring low power consumption and small size. Active RF Power Detector requires a 3.3V/5V DC supply, offering higher accuracy and faster response, but consumes more power. Passive detectors are ideal for lowcost, lowpower scenarios, while active detectors are preferred for highprecision applications.
Q: Can RF Power Detector measure both continuous wave and pulse RF signals?
A: Yes. Standard RF Power Detector models accurately measure CW signals. Fastresponse models with peak power detection function can capture pulse RF signals and calculate peak/average power. For special pulse signals, we provide customized detectors with optimized sampling circuits.
