P/N 61491A-1      ANTENNA INTERFACE ASSEMBLY

P/N 61491A-1 is a multi-channel receiver front end that matches the frequency sensitive complex impedance of an antenna to a 50 ohm load. The interface assembly has four open identical channels and one that is filtered to provide a multi-octave passband. Operational or BIT mode is selected by TTL. Interconnections are GPO blind-mate.
