GENERAL DESCRIPTION
n
PACKAGE OUTLINE
NJG1512V is a GaAs SPDT switch IC featuring high
isolation and low insertion loss.
This switch allows low operating voltage from 2.5V at
the wide frequency range from 1MHz to 3GHz.
NJG1512V is suitable to switch the synthesizer
signals between transmit and receiving circuit.
A very small SSOP package is adopted.
