Description

The FCC-250B-90-1.5-NFNF is designed to protect 1.45 – 1.6 GHz RF equipment from switching, lightning and electromagnetic pulse threats. It is designed to protect transmitters up to 10 watts of output power. This suppressor is constructed from proven connector, transmission line and gas discharge components.

It is capable of dissipating 10,000 ampere transients having an 8 μsecond rise time, and 20 μsecond half amplitude duration. The gas discharge tube can sustain several hundred of these transients if the time period between transients is suffi cient to let the tube cool. It is estimated that the tube will survive transients while dissipating 25,000 amperes. The DC breakdown or slow rising transients clamping voltage is 90 volts.

The nominal VSWR of this suppressor is 1.6:1 from 1.5 – 1.6 GHz. The insertion loss is nominally less than 0.25 dB over this frequency range. The design utilizes a short section of transmission line from input to output (DC path exists) for the center conductor, minimizing the phase shift experienced. The inner cavity of each suppressor is encapsulated with a lightweight, high temperature, low loss dielectric material that provides additional mechanical stability during shock and vibration.

The gas discharge tube utilized exhibit excellent linearity for RF signals. The twotone third order intermodulation intercept point has been measured in excess of +80 dbm.

The structure of the housing is brass, which is plated with a fused bright tin. The plating is in conformance with MIL-T-10727. This construction and plating ensures years of lasting performance, since the oxides of tin are conductive; grounding is always maintained even in a corrosive salt-spray environment.

This suppressor has been designed to withstand harsh environmental requirements. The gas tube will meet MIL-STD-202. The construction methods have been tested and demonstrate compliance to the following portions of MIL-STD-810C.
