P8AX Series 
Gas Discharge Tube
DC Pass
0 – 5 GHz (P8AX)
0 – 6.9 GHz (P8AX-6G)
|
Citel’s P8AX Series is a ultra low capacitance gas discharge tube (GDT) based surge arrestor designed for use in high frequency RF applications up to 6.9 GHz. The P8AX protects sensitive equipment connected to a single coaxial line from a direct lightning strike. The P8AX is installed in series with the line and has several standard grounding options including a grounding screw, mounting bracket or bulkhead.
The P8AX can be used in systems supplying up to +/- 48 volts DC via the coaxial cable and can be provided in 70, 500 and 1,000 watt versions for any 50 or 75 ohm network.

CNP Series

Hybrid Design
DC Block
125– 1000MHz
|
Citel’s CNP Series is a hybrid surge arrestor designed for use in low frequency RF applications from 125 to 1000MHz. The protection circuit utilizes gas discharge tubes (GDT), inductors, capacitors and metal oxide varistor (MOV). This CNP is best deployed in low frequency applications that require a very low residual voltage. The CNP is conveniently installed in series with the line and can be surface mounted via the flange, bulkhead or grounding screw.

CXF Series

Hybrid Design
DC Pass
0– 500MHz
|
Citel’s CXF Series is a hybrid surge arrestor designed for use in low frequency RF applications from 0 to 500MHz. The protection circuit utilizes gas discharge tubes (GDT) and metal oxide varistors (MOV). The CXF60 is best deployed in low frequency applications that require a very low residual voltage and brute force surge handling capability up to 20kA 8/20us.

PRC Series

Quarter Wave Stub (QWS)
DC Block
Specific Frequency Range |
Citel’s PRC Series is a Quarter Wave Stub (QWS) surge arrestor designed for specific frequency bands. The PRC does not utilize any active components and allows only the specified frequency to pass thus eliminating low frequency transients. This design allows for very high surge handling capacity up to 100kA 8/20us. The PR is conveniently installed in series with the line and can be mounted via the standard grounding screw or bulkhead.

UTPB Series

Quarter Wave Stub (QWS)
DC Block
Specific Frequency Range |
Citel's UTPB-1 Series is a single channel video balun with surge protection. These devices are used in CCTV systems that utilize UTP cable (Cat3/4/5/5e/6) for transmission runs as an alternative to coaxial cabling. These passive video transceivers can transmit real-time, full motion color or monochrome video signals over long distances.
