20 Apr 2010 Dept. of EECS. The Directional Coupler. A directional coupler is a 4-port network that is designed to divide and distribute power. Although this would seem to be a particularly mundane and simple task, these devices are both very important in microwave systems, and very difficult to design and construct.

A directional coupler is a passive device which couples part of the transmission power by a known amount out through another port, often by using two transmission lines set close enough together such that energy passing through one is coupled to the other. As shown in Figure 1, the device has four ports: input, transmitted
In today's microwave practice, the directional coupler has become a virtually indispensable measurement tool. It provides a simple, convenient, accurate means for sam- pling microwave energy without moving parts and without the need for adjustments. Unlike other methods of power sampling involving probes or coupling
23 Jan 2012 gENERAL DISCUSSION. A directional coupler inserted in a transmission line allows precise monitoring of the RF energy flow in that line while introducing minimum perturbation of the main line signal in the sampling process. Merrimac directional couplers are precision devices carefully designed for.
8 Sep 1999 The directional couplers offered by Mini-Circuits are designed for both commercial and military applications. All models are available in plug-in, flat-pack, surface mount, and connectorized SMA, BNC, Type N, TNC (option) packages. All units are designed and built to meet the environmental requirements
19 Jul 2010 This document contains the study of “Microwave directional couplers". Initiating with a waveguiding system, we are looking for solutions of Maxwell's equations, then we focus on the TEM Transmission Lines and we introduce the microstrip lines that are used to convey microwave-frequency signals. It.
Coupler. A key difference between couplers and power dividers is that couplers create a phase shift between the output signals. The main difference between directional couplers and quadrature hybrids is that directional couplers provide non-equal. Fig.2. Wilkinson power divider circuit diagram, amplitude response, phase.
