NJG1553F
1.5GHz/1.9GHz MIXER GaAs MMIC
n
GENERAL DESCRIPTION
NJG1553F is a mixer GaAs MMIC featured low distortion,
high conversion gain and low noise figure.
This mixer includes a local amplifier, and ideally suitable
for 1.5/1.9Hz band digital mobile phone and PHS handsets.
The very small MTP package is adopted.
