PACKAGE OUTLINE
NJG1304E is a GaAs MMIC designed mainly for driver
amplifier of PHS base station in Japan.
This is a variable gain type with 20dB dynamic range.
It features very low distortion and Pacp is less than 70dBc.
at 17dBm output power ,and enable low voltage and high
efficiency operation.
Small Plastic mold Package are adopted.
