Quantic PMI Model No. PSD-2G6G-CD-1 is High Power, Switch Box Assembly that provides protection to front-end receivers when in the presence of high-power signals. This is accomplished by sensing the input signal level and then switching the input signal into 50 ohms terminations when a set threshold level is exceeded. This assembly operates from 2.0 to 6.0GHz and can handle input power levels up to 10 Watts CW. The unit is supplied with an external 0 to 69dB step attenuator that can be used to adjust the signal levels feeding the internal threshold detector and thereby setting the trigger level of when the unit passes the input RF signal to the output of the switch assembly or when the signal is switched into the internal 50 ohms terminations. The switching speed is 50ns maximum. This unit operates on 110VDC, 50/60Hz and is supplied in housing that measures 15.0” x 10.0” x 4.0”. This unit is ruggedized and designed for harsh environments and is EMI shielded.
