800MHz BAND MIXER GaAs MMIC
nGENERAL DESCRIPTION nPACKAGE OUTLINE
NJG1551F is a mixer GaAs MMIC featured low
distortion, high conversion gain and low noise figure.
NJG1551F includes a mixer and a local amplifier,
and ideally suitable for 800MHz band digital mobile
phone handsets.
The very small MTP package is adopted.
