An attenuator is a passive broadband electronic device that reduces the 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 amplifier provides gain, an attenuator provides loss, or gain less than unity. An attenuator is often ...
RG-59 coaxial cable is commonly packed with consumer equipment, such as VCRs or digital cable/satellite receivers. Manufacturers tend to include only RG-59 cables because it costs less than RG-6 does. However, given the short lengths provided (usually 4–6 ft or 1.2–1.8 m), this is generally sufficient for its typical use.
An attenuator is a form of a two-port network with a generator connected to one port and a load connected to the other. In all of the circuits given below it is assumed that the generator and load impedances are purely resistive (though not necessarily equal) and that the attenuator circuit is required to perfectly match to these.
When the charging station is equipped with a permanently fixed cable, the connector end of the cable can be attached directly into the vehicle inlet, similar to using a petrol pump and when no fixed cable is available, a separate male-to-female cable is used to connect the vehicle, either using the charging station, or from a traditional IEC ...
The car will only charge at around 1 or 2 kW, which is five times slower than a home wallbox-style charger, and more than 100 times slower than what many electric cars are capable of.
Coaxial cable, or coax (pronounced / ˈ k oʊ. æ k s /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.
There also exist optical attenuators that decrease the signal in a fiber optic cable intentionally. Attenuation of light is also important in physical oceanography . This same effect is an important consideration in weather radar , as raindrops absorb a part of the emitted beam that is more or less significant, depending on the wavelength used.
SMA connectors must not be confused with the standard household 75-ohm type F coax connector (diameters: male 7 ⁄ 16 inch (11 mm) circular or hex; female 3 ⁄ 8 inch (9.5 mm) external threads), as there is only about a 2 mm difference overall in the specifications. Type F cannot be mated with SMA connectors without the use of an adapter.
