NJG1301V
MEDIUM POWER AMPLIFIER GaAs MMIC
nGENERAL
DESCRIPTION
NJG1301V is a medium power amplifier which is
designed for use of output stage of Japanese
PHS and digital wireless phone.
NJG1301V features low operating voltage, high
efficiency, and comes with, internal input and output matching
circuit and very small SSOP package. This amplifier is operated
up to 21dBm output level with very low noise generation.
