RF directional couplers have become a tool of choice for all types of RF measurements. RF directional couplers are used in a wide range of commercial and industrial applications, including communications, navigation and interconnect, diagnostics, instrumentation, high-fidelity audio, aerospace, and automotive. The HDH-00803GHD(40) is a high power, low insertion loss RF directional coupler.

The HDH-00803GHD(40) uses two (or more) identical coupled microstrip lines to form a directional coupler similar to a resistor-capacitor-inductor (RCL) network. Depending on the size of the step-up in line size and the length, the coupling factor can range from -30dB to 0dB. This makes it ideal for a variety of applications including high power communications, network analysis, antenna pattern measurements and wideband sampling.

The HDH-00803GHD(40) has a number of features that make it ideal for various applications. First, it is designed to handle high power with minimal insertion loss. The insertion loss of the HDH-00803GHD(40) is typically between 0.1dB to 0.8dB, making it suitable for use in high power applications. Second, it is highly reliable in terms of accuracy and durability, with a nominal accuracy of up to 1% over 40dB and an operational lifetime of up to 10 years. Third, the HDH-00803GHD(40) has a low noise figure, typically less than 1dB, making it ideal for applications requiring low signal-to-noise ratio. Finally, it has a high bandwidth of 75MHz to 1GHz, making it suitable for wideband applications.

The operating principle of the HDH-00803GHD(40) is based on the interaction between two (or more) coupled microstrip lines. A signal at the input is coupled to the output through the coupler, and the magnitude of the coupling is determined by the coupling factor. The coupling factor is related to the length and geometry of the coupled microstrip lines, and is adjusted by changing the lengths and widths of the lines. The degree of coupling is also affected by the distance between the two microstrip lines, which is normally fixed.

The HDH-00803GHD(40) is a high power, low insertion loss RF directional coupler suitable for use in a variety of commercial and industrial applications. Its low insertion loss, high reliability, low noise figure and wide bandwidth make it ideal for use in communications, navigation and interconnect, diagnostics, instrumentation, high-fidelity audio, aerospace, and automobile applications. Its operating principle based on the interaction of two (or more) coupled microstrip lines makes it adjustable to meet the specific requirements of any particular application.
