In radio engineering and telecommunications, standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide. Impedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the partial standing wave 's amplitude at an ...
The male contact was designed to be the same size as the cable conductor so that it could be used as the mating pin for optimized VSWR. Common applications included Mil-Aero, telecommunications, RFID, antennas, test and measurement and radar systems. SMZ connector – System 43 (BT43 and High Density HD43) for use in DDF. This is a 75 ohm ...
The following outline is provided as an overview of and topical guide to telecommunication: . Telecommunication – the transmission of signals over a distance for the purpose of communication.
Corrugated conical horn antenna used as a feed horn on a Hughes Direcway home satellite dish. A transparent plastic sheet covers the horn mouth to keep out rain. A horn antenna serves the same function for electromagnetic waves that an acoustical horn does for sound waves in a musical instrument such as a trumpet.
1G or (1-G) refers to the first generation of cellular network technology. These are the analog telecommunication standards that were introduced in 1979 and the early to mid-1980s and continued until being replaced by 2G digital telecommunications. The main difference between these two mobile telephone generations is that in 1G systems the ...
