In support of emerging mobile TV services—for which quality in-building and in-tunnel coverage will be essential—Radio Frequency Systems has expanded its ClearFill Line solution-set of passive Wireless INdoor Solutions (WINS).
ClearFill Line consists of purely passive RF distribution systems founded on RFS’s well-known broadband transmission line and radiating cable solutions. The introduction of new components optimized for broadband operation down to lower UHF frequencies (380 to 860MHz) completes the transition of ClearFill Line into the broadest ultra-broadband solution on the market.
According to Peter Raabe, RFS Director Global Product Management and Support for WINS, “closing the UHF gap” represents the final evolution stage for the passive distributed antenna systems (DAS) at the heart of ClearFill Line. “RFS now offers the broadest ultra-broadband passive DAS on the market,” he said. “ClearFill Line delivers premium coverage solutions for all emerging and existing wireless applications—from digital video broadcast to handhelds (DVB-H) in UHF frequencies to worldwide interoperability for microwave access (WiMAX).”
The expanded ClearFill Line suite includes a new ultra-broadband omni indoor antenna (model I-ATO1-380/6000) which has an operating range of 380MHz to 6GHz. Extremely lightweight at just 400g (0.9lb), the ultra-broadband omni’s power rating of 50W makes it ideal for multi-service operation in an indoor environment.
New models of directional couplers and power dividers, supporting frequencies between 380 and 2700MHz, have also been added. These new elements all exhibit excellent passive intermodulation (PIM) performance and a high power rating to support multiple services.
- Hybrid coupler (3dB)—achieving high isolation between two combined signals
- Directional couplers (6, 10 and 15dB)—achieving constant coupling ratio across the entire frequency range
- Power dividers (2-, 3- and 4-way)—exhibiting low insertion loss for optimum performance
These new elements complement the balance of the ClearFill Line ultra-broadband solution-set, which includes: ultra-broadband power dividers (350MHz to 6GHz), RADIAFLEX radiating cable and CELLFLEX transmission line.
