NJG1309VB2
TRANSMITTING POWER AMPLIFIER
GaAs MMIC
nGENERAL
DESCRIPTION
NJG1309VB2 is a positive voltage supply type GaAs power
amplifier MMIC designed for Digital Cordless Phone.
Gate bias and Gain control bias terminals are supplied
by positive voltage.
These terminals have high-impedance characteristics.
NJG1309VB2 can reduce power
consumption at receiving mode by “Standby Function”.
