FAKRA connector is a modified SMB connector with a keyed and colour coded plastic housing and latch, used in the automotive industry [5] SMC connector; SSMA connector is a 50 Ohm nominal impedance RF connector which utilizes a 10–36 threaded coupling and is essentially a scaled down version of the SMA. They are characterized by compactness ...
Diagram of leaky feeder cable. A leaky feeder is a communications system used in underground mines and inside tunnels. [1] Manufacturers and cabling professionals use the term "radiating cable" [2] [3] [better source needed] [4] as this implies that the cable is designed to radiate: something that a typical coaxial cable is generally not intended to do.
Research activity in the area of radio-frequency circuit design has surged in the 2000s in direct response to the enormous market demand for inexpensive, high-data-rate wireless transceivers. [ 2 ] Common types of RF connectors are used for television receivers, two-way radio , certain Wi-Fi devices with removable antennas, and industrial or ...
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
The UHF connector [4] is a name for a fairly common, but old type of threaded RF connector. [5] [6] The connector design was invented in the 1930s for use in the radio industry. [7] [4] It is a widely used standard connector for HF transmission lines on full-sized radio equipment, with BNC connectors predominating for smaller, hand-held ...
The F connector is an inexpensive, gendered, threaded, compression connector for radio frequency signals. It has good 75 Ω impedance match for frequencies well over 1 GHz [2] and has usable bandwidth up to several GHz. Connectors mate using a 3/8-32UNEF thread. The female connector has a socket for the center conductor and external threads.
Peak pulse power handling, driven by voltage breakdown, is more or less frequency independent for any given size (and can be deduced by assuming ~300 V RMS per mm of inner to outer spacing), but the average power, limited by losses heating the centre conductors, increases approximately with the square root of the operating frequency.
In a radio antenna, the feed line (feedline), or feeder, is the cable or other transmission line that connects the antenna with the radio transmitter or receiver.In a transmitting antenna, it feeds the radio frequency (RF) current from the transmitter to the antenna, where the energy in the current is radiated as radio waves.
