FE4001 L-Band Triple-Band Filter
The Asartech FE4001 combines three L-band passbands in a single filter for LINK16 and TACAN applications. Sharp transitions between its passbands and rejection regions suppress unwanted IFF signals at 1030 and 1090 MHz.
The filter provides low passband insertion loss and at least 60 dB rejection at the specified IFF frequencies. Two SMA female connections and a compact enclosure provide a connectorized filtering solution for multiband RF assemblies.
