Quarter-wave protective devices

9 April 2003 Circuit & System Protection News & Events

Citel's PRC protectors use 'quarter-wave' technology. The quarter-wave stub and other mechanical elements are carefully designed according to the operating frequency band to realise a band filter (narrowband or wideband). Since the lightning surges have a low frequency spectrum (from a few hundred kHz to a few MHz) they will be filtered out from the operating frequencies.

PRC protectors provide a very high level of protection against lightning surges and have a very low residual voltage. Also, they can tolerate multiple lightning strikes and require no maintenance.

They are available for various wireless applications (different frequency range) and available connectors are: 7/16, N, TNC and direct 7/8" cable entry (bulkhead version available in all types of connectors).

Materials are: housing - copper alloy with CuZnSn finish; contact - silver-plated copper alloy (beryllium copper as option); insulation - Teflon.
