Expanded line of 7/16 DIN quarter-wave surge protectors

PolyPhaser has released a new quarter-wave RF surge protector to guard equipment against EMP and power surges caused by lightning or other strong electrical changes.

The new QWP-DMDF-ER coaxial surge protector provides an extended frequency range, supporting 555MHz to 4.5GHz while suppressing DC surge. This broadband performance makes it ideal for applications including CBRS networks, cellular networks, DAS, emergency response systems and public safety systems. This new 7/16 DIN surge protector also includes quarter-wave stub technology to protect equipment at up to 200W of maximum input power.

This coax surge protector features a male 7/16-inch DIN input and a female 7/16 DIN output. It has low let-through energy and supports low PIM levels up to 160dBc along with a DC block topology.

“Our new extended range 7/16 DIN RF surge protector provides a high-performance, low let-through energy solution. It allows our customers to maximize the reliability of their CBRS and cellular networks and ensures critical communication systems continue operating through potentially damaging lightning storms,” said Dan Rebeck, product line manager.
