The last few years have seen steady expansion of network infrastructure to accommodate new frequencies, and investments in new equipment have gone sky-high as a result. Many operators have installed a wide variety of new devices, all of which need to be safeguarded and efficiently managed. The new SPINNER Power Protector prevents the master unit from being damaged by high power while greatly helping to reduce capital expenditures.
New communications applications involving the N 75 Ohm interface operate at high frequencies up to 18 and 20 GHz. This has created a need for precise, reliable test equipment for calibration and connection to available 50 Ohm vector network analyzers. SPINNER has now launched high-precision calibration kits in both cased and compact 4-in-1 formats, as well as adapters ranging from N 75 Ohm to N 50 Ohm (DC - 18 GHz) and 3.5 mm 50 Ohm (DC - 20 GHz).
SPINNER already excels with an outstanding portfolio of combining and distributing products for efficient, cost-effective implementation of in-building projects. They include CPR jumpers and cables, splitters, tappers and couplers. And now we have taken it to the next level by adding antennas. This paves the way for building entire distribution antenna systems (DAS) with high-quality components from a single source: SPINNER.
Transmitter power levels in the USA are among the highest in the world. SPINNER supplies many of its signature products in sizes up to 9 3/16”, including the patented Antenna Monitoring System (AMS) and our original Direct Access Units. Our switches already had the highest power handling for any given line size but now we have taken it even further and introduce the world’s first 8-3/16” switch. With a walloping 120 kW of power handling this switch is a viable alternative to waveguides.
SPINNER will be exhibiting at the NAB Show 2019 in Las Vegas from April 08–11, booth C1336.
SPINNER has advanced into a new dimension by creating the first series produced 8 3/16” coax switch. It is designed for an operating frequency of up to 620 MHz and can transfer 120 kW of power at this frequency. The maximum power handling of 950 kW could be operated within the range between DC and 10 MHz. The switch is suitable for 75 ohm systems. Used in coaxial rigid lines, it eliminates the waveguide switches and adaptors that are normally required for this power level. Other advantages over waveguide switches include its broadband capabilities and compact shape.
