MRF1K50GN
These high ruggedness devices are designed for use in high VSWR industrial,
scientific and medical applications, as well as radio and VHF TV broadcast,
sub--GHz aerospace and mobile radio applications. Their unmatched input and
output design allows for wide frequency range use from 1.8 to 500 MHz.
