NJG1552F
1.5GHz/1.9GHz MIXER GaAs MMIC
nGENERAL
DESCRIPTION
NJG1552F is a mixer GaAs MMIC featured low power
consumption, 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.
