Analysis example of a porous directional coupler.

While suppressing the losses of the guiding wave tube, branch the wave and measure the reflected power ratio, etc., in the sub-guiding wave tube.

The porous directional coupler is a coupler with numerous coupling holes created in two waveguides (WRJ-10) that share the E-plane, demonstrating good directionality over a wide bandwidth. We analyzed the electromagnetic waves within the waveguide when 10 GHz microwaves (TE10) were incident at the ports of the waveguide. The diameter of the holes is larger closer to the center, and the center positions of the holes are arranged at intervals of one-quarter of the wavelength within the tube. For more details, please download the catalog.

Coaxial Directional Coupler "Model 6000"

Despite its small size, it has good directionality! Two types are available: one for high directionality measurements and one for general use.

We handle the coaxial directional coupler "Model 6000." It operates in frequency bands below 1000MHz, and due to the long coupling section, it utilizes a stripline structure with dielectric materials to maintain mechanical strength. One end of the auxiliary line is terminated at 50Ω, while the other end is an N-type jack, allowing for good directionality despite its small size, and it is designed to handle large passing power. 【Features】 ■ Structure that maintains mechanical strength using dielectric materials ■ Designed to handle large passing power *For more details, please refer to the PDF document or feel free to contact us.

About directional couplers

[Application Example] This explains the measurement of traveling wave power using a 3-port directional coupler as an example.

■Signal Analyzer MSA500 Series A handheld signal analyzer that combines real-time and sweeping methods (real-time spectrum analyzer). By incorporating both real-time method using fast Fourier transform (FFT) and the traditional sweeping method, it is possible to utilize the advantages of both approaches. ■Spectrum Analyzer MSA400 Series Compact, lightweight, and low-cost. A full-fledged spectrum analyzer with performance and functionality that rivals large bench-type models. Directional couplers are used to measure the power of the forward wave entering from the input port. For example, in the diagram below, there is a power monitor when connecting an RF signal generator to an antenna to transmit radio waves. This example explains the directional coupler.

[Information] Directional Coupler: Its Operation and Applications

It is one of the important signal processing devices! We will also introduce examples of applications for directional couplers and bidirectional couplers!

This document introduces the "Directional Coupler." Its basic function is to monitor RF signals with high isolation between the signal port and the monitor port, supporting the analysis, measurement, and processing of various applications based on a specified coupling degree. Since the directional coupler is a passive device, it operates in the reverse direction as well, where the signal couples with the main path signal depending on the device's directionality and coupling degree.
