Resonant inductive coupling - Wikipedia
Resonant inductive coupling or magnetic phase synchronous coupling is a phenomenon with inductive coupling where the coupling becomes stronger when the "secondary" (load-bearing) side of the loosely coupled coil resonates. A resonant transformer of this type is often used in analog circuitry as a bandpass filter.Resonant inductive coupling is also being used in wireless power systems for ...

Application Note: Directional Couplers
08.09.1999 · Especially designed for high power applications, the H series of directional couplers can operate with up to 25 watts of RF input. Mini-Circuits directional couplers are reactive devices featuring very low insertion loss. Most models have 3 ports, and are manufactured with an internal 50-ohm termination. In these cases, power coupled from any power incident to the output port (the reflected ...

RF design and analysis requires an understanding of the complex ways in which high-frequency signals move through a real circuit. RF design is known to be particularly challenging among the various subdisciplines of electrical engineering. One reason for this is the extreme inconsistency between theoretical electrical signals and high-frequency ...

Couplers are not as widely used as some RF components like attenuators, mixers and the like, but in areas closer to the antenna where power may need to be sampled, they are widely used. For example a directional coupler may be used within a meter detecting the standing wave ratio, but they also have many other applications.
CHAPTER - IK4HDQ Radio Air Sat
Radio-frequency (RF) electronics differ from other electronics because the higher frequencies make some circuit operation a little hard to understand. Stray capacitance and stray inductance afflict these circuits. Stray capacitance is the capacitance that exists between conductors of the circuit, between conductors or components and ground, or between components. Stray …
Radio frequency - Wikipedia
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz.This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies; these are the frequencies at which energy from an oscillating ...

Orthomode transducer - Wikipedia
VSAT and Satellite Earth Station Applications. For VSAT modems the transmission and reception paths are at 90° to each other, or in other words, the signals are orthogonally polarized with respect to each other. This orthogonal shift between the two signal paths provides approximately an isolation of 40 dB in the K u band and K a band radio frequency bands.

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 ...
