1Metamaterial 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… …
2Power 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 …
3HYPERFRÉQUENCES — D’après la définition la plus couramment admise, les hyperfréquences représentent des ondes électromagnétiques dont la longueur d’onde est de l’ordre du centimètre, et que l’on utilise notamment en technique radar et en transmission hertzienne.… …
4Antenna (radio) — Whip antenna on car …
5Attenuator (electronics) — An attenuator is an electronic device that reduces the amplitude or power of a signal without appreciably distorting its waveform.An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an… …
6Differential signaling — This article is about electric signals via wires. For an immunological model attempting to explain how T cells survive selection during maturation, see Differential Signaling Hypothesis. Differential signaling is a method of transmitting… …
7Delay line memory — Computer memory types Volatile RAM DRAM (e.g., DDR SDRAM) SRAM In development T RAM Z RAM TTRAM Historical Delay line memory Selectron tube Williams tube …
8Dipole antenna — A schematic of a half wave dipole antenna connected to an unbalanced coaxial cable. Better practice is to connect the balanced dipole to the unbalanced line with a balun. A dipole antenna is a radio antenna that can be made of a simple wire, with …
9Satellite television — List of digital television broadcast standards DVB standards (Europe) DVB S (satellite) DVB S2 DVB T (terrestrial) DVB T2 DVB C …
10Differential pair — A differential pair is a pair of conductors used for differential signaling. Differential pairs are usually found on a printed circuit board, in cables (twisted pair cables, ribbon cables), and in connectors. The term can also refer to a pair of… …
