Model PSD-6G16G-CD-1 is a high-power switch assembly that that can protect sensitive components and systems (such as receivers) when in the presence of high-power signals.It does this by sensing input signal levels and switching input signals to 50-Ω terminations when a threshold level has been exceeded. The switch assembly is designed for power levels as high as 10 W continuous wave (CW) across a frequency range of 6 to 18 GHz. It is supplied with an external step attenuator with range of 0 to 69 dB to adjust signal levels for the threshold setting (and therefore the trigger level for the switch assembly). The assembly achieves switching speed of 50 ns maximum and operates on 110 VAC. It is supplied in a housing measuring 15.0 x 10.0 x 4.0 in. and is shielded for electromagnetic interference (EMI) and designed for harsh environments.
