Power dividers and directional couplers — A 10 dB 1.7–2.2 GHz directional coupler. From left to right: input, coupled, isolated (terminated with a load), and transmitted port … Wikipedia
Power duo — is a name sometimes given to two piece rock bands consisting of just an electric guitarist and a drummer, particularly those who follow a similar blues rock style to a traditional power trio, for example the White Stripes and the Black Keys. A… … Wikipedia
Wilkinson power divider — In the field of microwave engineering and circuit design, the Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports. The… … Wikipedia
Metamaterial antenna — This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the Z element inside the square that acts as a metamaterial, greatly… … Wikipedia
Radio repeater — A radio repeater is a combination of a radio receiver and a radio transmitter that receives a weak or low level signal and retransmits it at a higher level or higher power, so that the signal can cover longer distances without degradation. This… … Wikipedia
Diplexer — A diplexer is a passive device that implements frequency domain multiplexing. Two ports (e.g., L and H) are multiplexed onto a third port (e.g., S). The signals on ports L and H occupy disjoint frequency bands. Consequently, the signals on L and… … Wikipedia
Microstrip — Cross section of microstrip geometry. Conductor (A) is separated from ground plane (D) by dielectric substrate (C). Upper dielectric (B) is typically air. Microstrip is a type of electrical transmission line which can be fabricated using printed… … Wikipedia
Hybrid coupler — A hybrid coupler is a passive device used in radio and telecommunications. It is a type of directional coupler where the input power is equally divided between two output ports. For further information see Power dividers and directional… … Wikipedia
