CSP - Coaxial Surge Protection

The Coaxial Surge Protector (CSP) family of surge diverters is designed to offer robust and reliable protection from transients on coaxial antenna RF feeder cables. They are comprised of a leadless gas arrestor housed in a chrome plated brass block. Careful design and precision machining has allowed the match between the characteristic impedance of the unit and the cable to be optimized. This attention to detail has resulted in a unit capable of operating at typical power and frequency levels of 900W and 3GHz respectively, while minimizing the insertion and return losses.

Features

Simple plug-in installation

Supplied with adjustable right angled grounded mounting block or flying lead ground.

Low Insertion and Return Loss

Wide Operating Frequency Spectrum

Field serviceable, with replaceable gas arrestor

Applications

Bulkhead mount

A convenient mechanical arrangement for termination and protection of coaxial cables at a comunication site's point-of-entry

In-Line installation

Generally used for direct connection to the radio equipment antenna port, or in line with the coaxial feed

Note: To select the appropriate protection voltage, use the following procedure:

Determine the transmitter power in Watts (P).

Determine the VSWR. If unsure, use 1.5.

Vpeak = VSWR x 1.4 x sqrt (50P).

If Vpeak < 72V, use CSP XXX 90.
If Vpeak >72V and < 480V, use CSP XXX 600.

Taking this value of VSWR and allowing a little margin, this means that typically the 90V protector is used for Receivers and Transmitters up to 20W, while the 600W protector can be used for transmitters up to 900W.
