How does a directional coupler work?
A directional coupler is an electronic component having four-port circuits with one port being isolated from the input port and another being considered as a through port. The device is normally used to split the input signal and distributed power.
An RF Splitter/Combiner is a transmission component which divides or sums power between two or more ports. Typically they are used for connecting more than one antenna to a single radio and can also be used to connect multiple radios to a single antenna using the same frequency.
- 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.
- The higher the frequency of the signal passing through the coaxial cable, the higher the loss over a given length. Coaxial cable loss is normally specified in dB loss per 100 feet of cable.
- Optics. Attenuation in fiber optics, also known as transmission loss, is the reduction in intensity of the light beam (or signal) with respect to distance travelled through a transmission medium. Empirical research has shown that attenuation in optical fiber is caused primarily by both scattering and absorption.
Power Divider Function. The power divider is a separate differential box located between the already existing two differential boxes at the rear end of the truck. This differential can be locked and unlocked by the driver in situations when there is little or no traction for the drive wheels.
- The differential is what allows the wheels to turn at different speeds. The vast majority of rear-wheel drive cars have an open differential. This means that the rear wheels can spin independently of each other. If it spins in the same direction, you have a limited slip differential, or LSD.
- Wheels receive power from the engine via a drive shaft. The wheels that receive power and make the vehicle move forward are called the drive wheels. The main function of the differential gear is to allow the drive wheels to turn at different rpms while both receiving power from the engine.
- The automotive differential is designed to drive a pair of wheels while allowing them to rotate at different speeds. In vehicles without a differential, such as karts, both driving wheels are forced to rotate at the same speed, usually on a common axle driven by a simple chain-drive mechanism.
