Additionally, it is used in military, aerospace, and automotive applications.

Working Principle: The HDH-01503GHD(31) RF Directional Coupler uses a two-port RF splitter to split the RF signal into two different paths. The signal is fed to the first port of the coupler and then passes through the coupling loop, which is a high-Q element consisting of a pair of series capacitors and a shunt inductor. This loop acts as a directional sampler, sampling the incoming signal and splitting it into two different paths. The signal from the incoming port is passed to one of these two paths, and the signal is reflected and passed to the other path.

The two paths are then connected to a pair of matched directional coupler networks that measure the power of the incoming signal. The coupler networks are composed of two series capacitors and one inductor, and the incoming signal is passed through these components to measure and monitor the power level. The directional coupler is then calibrated, and from the calibration data it is possible to determine the power of the incoming signal.

The HDH-01503GHD(31) RF Directional Coupler is highly accurate and reliable and performs well at a wide range of frequencies, from 800MHz to 5.6GHz. Additionally, it is designed to minimize signal loss and has good temperature stability for reliable performance. The coupler is also field-proof and cost-effective, making it an ideal choice for applications that require accurate and reliable power level measurements.

In conclusion, the HDH-01503GHD(31) is a practical and effective tool for measuring and monitoring RF power levels in radio communication systems. Its highly accurate, reliable, and robust design makes it a suitable choice for a variety of applications that require accurate and dependable power measurements. With its wide operating range and field-proof design, it is a cost-effective choice for any application that requires precise power level measurements.
