Quantic PMI Model No. ADM-1018G-SFF-110VAC is a state-of-the-art 10 MHz to 18.0 GHz integrated subsystem that allows users to input RF signals and provide automatic detection when signal levels fall below -30 dBm and automatically switch in a low noise amplifier such that low level signals can remain detectable. The purpose of this module is to provide optimum RF signal levels to a RF/fiber converter module. The unit is powered by standard 100 VAC. The RF input is via a sma female connector and the output is via a sma female connector. the product is configured such that the end user can change the value of the fixed attenuator level by changing the internal sma screw-on attenuator such that in system optimization can be done.
