At PolyPhaser we always get a kick out of hearing someone refer to a surge protector as “a PolyPhaser.” It’s gratifying to have earned a reputation among many for producing the best RF surge protectors on the market.
But we are not resting on our laurels. In recent years we’ve applied our pursuit of innovation and improvement towards a new line of RF interconnects. They include two types of cable assemblies – ones that complement our surge protectors, and models with in-line surge protection. Both are ideal for use in building out your communications networks, providing connections and protection to connected devices. Their applications include the following:
- Tower-top equipment in telecommunications base stations
- Land mobile radio (LMR) and other communications
- Antenna installations/IEEE 802.11a/b/g/n/ac, DAS
- Cellular and Wi-Fi systems
- 4G and 5G networks
- Lab use
Below are some features of our coax cable assemblies that we believe you will find useful:
Low-Loss Cable
PolyPhaser’s cable assemblies are made with low-loss, LMR-equivalent coaxial cable that meets the demands of wireless applications, including WLAN, cellular, PCS and ISM, and supports operating frequencies all the way up to 5.8 GHz. The solid center conductor is surrounded by a foam polyethylene dielectric that provides less attenuation than solid dielectric coax, with a phase velocity of either 80% or 85%. Just inside the cable’s PE jacket is a double shield that provides >90% shielding.
Integrated Surge Protection
Our coax cable assemblies with surge protection built in feature a Type N connector on one end and an in-line multi-strike surge protector with replaceable gas tube element on the other. The protector is attached directly to the cable. The combination of the low-loss cable and the integrated surge protection connector results in excellent low insertion loss and return loss by reducing the amount of additional hardware required. Having fewer parts also lowers your cost and makes installation easier. These coax cables are constructed using 400 series coax cable which is renowned for its low loss but lightweight and flexible enough for easy installation.
Low PIM All the Way
If you mix two or more frequencies on the same cable, you can get interference in the form of passive intermodulation, or PIM. For instance, PIM might result from combining the signals from multiple antennas in a cell tower. Keeping PIM, which is measured in decibels, down to acceptable levels requires a network that utilizes low PIM cables, connectors and surge protectors throughout the network. PolyPhaser stocks a large selection of low-PIM RF cable assemblies to address applications where PIM can cause a problem.
Connector Options
The cable assemblies that complement our surge protectors are available with popular connector options, including Type-N, SMA, UHF, TNC and 7/16-inch. The assemblies with in-line surge protection feature robust Type-N connectors and a bulkhead option. We also carry a line of non-shorting dust caps to protect your precision connectors from contaminants as well as current spikes caused by electrostatic discharge.
