PolyPhaser’s two new additions have 2.2-5 and 4.3-10 connectors

February 23, 2023

IRVINE, Calif.—PolyPhaser recently added two extended-range RF surge protectors with 2.2-5 and 4.3-10 type connectors to its line of quarter-wave stub designs. The new devices protect all major cell bands up to the Citizens Band Radio Service (CBRS) at 4.2 GHz, the company said in a release.

PolyPhaser is an Infinite Electronics brand and a provider of RF and data surge protection, filtering, and grounding products. The company said its new low-PIM surge protectors offer male/female 2.2-5 type connectors and female/female 4.3-10 type connectors.

The connectors are solid and reliable, yet light and compact, and they support the requirements for a system-level PIM rating of 160 dBc. The quarter-wave stub protection technology supports a lower let-through energy rating, a key performance requirement for surge protection, according to PolyPhaser.

These repetitive-strike surge protectors suppress DC surge while featuring a pass band of 555 MHz to 4.5 GHz, which is compatible with cellular bands and the CBRS. Applications include radio and antenna installations for telecom, public safety, and emergency response, where some or all system equipment is outdoors, the company said.

The low-PIM surge protectors are designed to help protect equipment from electromagnetic pulse (EMP) or power surges that are commonly caused by lightning or other strong electrical changes. They are said to protect equipment at up to a maximum power handling of 200 watts.

“These extended-range RF protectors provide a single solution for protection for all major cell bands up to CBRS,” said Dan Rebeck, product line manager at PolyPhaser, in the release.
