PolyPhaser has added two extended-range RF surge protectors with 2.2-5 and 4.3-10 type connectors to its quarter-wave stub design line. The new devices protect all major cell bands up to the CBRS at 4.2GHz.
The new low-PIM surge protectors provide 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 need for a system-level PIM rating of 160dBc. The quarter-wave stub protection technology provides a lower let-through energy rating, a key performance necessity for surge protection.
These repetitive-strike surge protectors suppress DC surge while providing a pass band of 555MHz to 4.5GHz, compatible with cellular bands and the CBRS. Ideal applications comprise radio and antenna installations for telecom, public safety and emergency response, where some or all system equipment is outdoors.
The low-PIM surge protectors are created to help protect equipment from EMP or power surges often caused by lightning or other strong electrical changes. They protect equipment at up to a maximum power handling of 200W.
“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.
