Forward-Wave Versus Backward-Wave CouplersGeneric Directional Coupler Schematic SymbolDirectional Coupler DefinitionsBethe-Hole CouplerMulti-Hole CouplerBi-Directional PropertyDual-Directional CouplerHybrid CouplersReflectometerNew for January 2013: we will further describe the simple difference between forward and backward wave coupling. In the forward-wave coupler, energy that propagates down transmission line starts a parallel wave down transmission line 2 as shown below. The most common forward coupler is the multi-hole coupler realized in waveguide. In this case the holes are spaced a quarter wave apart so that the reverse wave cancels out. Flat coupling across a wide bandwidth is possible, using a lot of math..See more on microwaves101
Optocoupler Circuits | Nuts & Volts Magazine
An optocoupler device can be simply described as a sealed, self-contained unit that houses independently-powered optical (light) Tx and Rx units, that can be coupled together optically. Figure 1 shows the basic form of such a device. Here, the Tx unit is a [PDF]
Application Note: Directional Couplers - Mini-Circuits
A schematic representation of the coupler is as follows; the arrows show signal flow: Key characteristics of a directional coupler include coupling coefficient, coupling flatness, main-line loss and directivity, defined on the next page.[PDF]
Microwave Power Dividers and Couplers Tutorial
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[PDF]

Power dividers and directional couplers - Wikipedia
Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit. An essential feature of directional couplers is that they only couple power

Opto-isolator - Wikipedia
Schematic diagram of an opto-isolator showing source of light (LED) on the left, dielectric barrier in the center, and sensor (phototransistor) on the right. [note 1] An opto-isolator (also called an optocoupler , photocoupler , or optical isolator ) is an electronic component that transfers electrical signals between two isolated circuits by
