SDLVA-3G18G-CW-70-MAH

PMI Model No: SDLVA-3G18G-CW-70-MAH is a CW-immune successive detection log video amplifier operating in the 2.0 to 18.0 GHz frequency band.  It features an SPST on the RF output which allows for the RF to be blanked when the RF input signal is below the -64 dBm threshold.

In addition to RF blanking, a 3.3V TTL-compatible output is also provided for time-gating or sampling to assist in digital system integration.
