Extractors

Asartech’s extractor technology combines multiple L-band passbands with rejection of unwanted signals between the operating bands. Developed for LINK16 and TACAN frequencies, the filtering design suppresses signals in the IFF bands and provides sharp transitions between passbands and rejection regions. A machined enclosure and SMA female connections provide a connectorized solution for communications assemblies requiring selective multiband filtering.

• Passbands of 960–1010, 1050–1072 and 1110–1215 MHz
• Maximum passband insertion loss of 2 dB
• Minimum rejection of 60 dB at 1030 and 1090 MHz
• Minimum passband return loss of 16 dB
