S-Band Radar Front End
NJS 4310D
NJS4310D is designed for the front end of radar system.
It features a small size and a light weight operable at any frequency
between 3.02GHz and 3.08GHz
This front end module consists of GaAs FET low noise amplifier. image
rejection mixer. 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.
