JRC NJT1949A X-Band Front-End Module is designed for the front end of marine radar system.
JRC NJT1949A X-Band Front-End Module features a small size and a light weight operable at any frequency between 9.415GHz and 9.475GHz.
This front-end module consists of GaAs FET low noise amplifier, Image rejection mixer and Local VCO with buffer amplifier.
FET monitoring circuit is included to monitor FET drain current.
The stability of the local VCO frequency by the input RF power is increased effectively by the buffer amplifier which is located between image rejection mixer and local VCO.
