JRC NJT1947B X-Band Front-End Module

JRC NJT1947B X-Band Front-End Module

JRC NJT1947B X-Band Front-End Module is designed for the front end of marine radar system.

Description

JRC NJT1947B X-Band Front-End Module features a small size and a light weight operable at any frequency between 9.38GHz and 9.44GHz.

This front end module consists of PIN diode Limiter, GaAs FFT low noise amplifier, Image rejection mixer, Local VCO with buffer amplifier.

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.
