RF Directional Couplers are a type of device designed to measure the power of a radio signal without actually measuring it directly. When used in this application, a directional coupler sends a sample of the signal to an external power meter, while the remainder travels along its intended path. The 1H0263-3 directional coupler is a useful device for measuring the power from a radio transmitter, as it features two unique sections with different split ratios. This extends the range of power that can be accurately measured. The following outlines the field of application and working principle of the 1H0263-3.

The 1H0263-3 RF Directional Coupler is ideal for use in applications requiring the measurement of radio signal strength in excess of 100 watts. It is therefore often employed in repeater stations, base stations, transmitters and receivers. Additionally, it is an excellent choice when testing the power of transmitted signals, as the two sections allow for multiple split ratios. This allows for a stronger, more accurate measurement of signal strength than a single section Directional Coupler.

The 1H0263-3 is also well suited to applications where the power of signals changes rapidly. This is because of its two section design which allows for varied power measurement over short time periods. As the power of the signal fluxuation is measured over two separate connections, this measurement of signal power is fast and reliable. Additionally, it is commonly used in applications where the signal power is expected to change rapidly as it also features a rapid signal detection capability.

The working principle of the 1H0263-3 RF Directional Coupler is based on the concept of power splitting. By splitting the incoming signal into two portions, the signal can then be measured independently by two separate instruments. The two sections split the signal in to two unequal parts, respectively. The larger portion of the signal passes straight through while a smaller portion is diverted to the power meter. The power meter measures the strength of the signal, allowing for a more accurate measurement of the overall strength and power of the signal.

The 1H0263-3 RF Directional Coupler is an effective and efficient device for measuring the power of an RF radio signal, particularly when the power level changes within a short time frame. This is because of its two section design which allows for fast, accurate measurements. Its split ratios also enable more accurate measurements over a wider range of power. Its flexibility and ease of use make it an ideal choice for measuring radio signal strength in applications such as repeater stations, base stations, transmitters and receivers.
