ETL Systems to show GPS over fibre system
At IMS, ETL will display its expanded portfolio of RF and microwave products, which now includes GPS over Fibre and other Global Positioning System (GPS) / Global Navigation Satellite System (GNSS) products such as GPS lightning arrestors, GPS line amplifiers, GPS splitters and GPS attenuators. Typical fields of application for these products include Position, Navigation and Timing (PNT).
RF components from ETL Systems were recently utilized in the building of Timeline Television’s first UHD production truck for use with major UK broadcasters. ETL components were also selected by ND SatCom to upgrade a VSAT system for an air traffic control provider in Africa.
“ETL’s GPS/GNSS over Fibre can transport a GPS signal from an antenna to a GPS receiver up to 10km away and the outdoor transmit unit features an IP65 rated weatherproof housing with flexible mounting options,” said Dominic Overton, Components Sales Executive, at ETL Systems. “With the news that Fiber-Span has gone out of business, we want to let their customers know we can support them.”
The company’s GPS over Fibre is provided with short circuit protected 12-V 500-mA antenna power, with LED indicators for module and antenna power and status. Single or dual redundant external power supplies are available as an option, and the indoor receive modules feature antenna fail alarm pass through and can be provided as standalone units or housed in a 19-inch rack mount chassis, which can hold up to four modules.
Rounding off ETL’s expanded portfolio are new RF and microwave custom filters, an outdoor range of components and waveguide assemblies.
ETL is able to offer custom RF and Microwave filters for 50Ω or 75Ω impedances and various connector types for many fields of application, including: telecom infrastructure, satellite systems, microwave links, test and instrumentation, cellular applications, military communications and radar networks. The company can supply cavity bandpass filters working within a frequency range of 100 MHz to 40 GHz and also microstrip filters, including suspended substrate technologies, for broadband performances covering frequencies within DC to 20 GHz.
“We are seeing an increasing number of customer requirements for L band components to be installed outdoors in weatherproof housings for satcom applications, which is why ETL is expanding its range of standard RF components IP65 and IP67 rated for outdoor applications to now include RF splitters/combiners, couplers, multiplexers, bias tees, impedance transformers, and line amplifiers,” said Overton.
ETL Systems also now offers precision made waveguide components for RF and microwave systems, which are all made to the highest quality standards and use International Flange styles and finishes to suit. Components are available in aluminium, brass or copper waveguide with aluminium or brass flanges fitted. Frequency ranges up to 40 GHz, and WR-650 to WR-28.
