CN-LAMBDA/4-2.2... COAXTRAB Surge Voltage Protection for Mobile Phone and Broadband Communication Systems TRABTECH Data Sheet 2431_en_A (c) PHOENIX CONTACT - 01/2009 Description The CN-LAMBDA/4-2.2... with N-type connector protects radio devices against surge voltage. Placed on both sides of the device being protected, transient voltages are prevented from damaging equipment. With its high energy-absorbing capacity, the CN-LAMBDA/4-2.2... greatly reduces system failure when using exposed antenna systems. /4 /4 The Lambda/4 technology provides excellent protection with limited signal degradation. Compatible with 0.82 to 2.2 GHz signals, the adapter is ideal for protecting mobile phones and satellite location systems. For maximum protection, install a CN-LAMBDA/4-2.2... at each coaxial input and output connector to protect a device against both lightning strikes and transient voltage picked up by the cable. The adapter includes a seal for mounting through a 16 mm diameter hole in a bulkhead. An optional mounting bracket allows mounting to a plate. Grounding is through the bulkhead, optional bracket or separate wire (up to 4 AWG/25 mm2) attached to the grounding lug (requires user-supplied M8 screw).
