GENERAL DESCRIPTION
n
PACKAGE OUTLINE
NJG1507R is a GaAs SPDT switch IC which exhibits low
loss and high isolation, and ideally suitable for T/R switch of
the digital wireless phone.
This switch is operated in the wide frequency range from
50MHz to 3.0GHz at low operating voltage from +2.5V with
small VSP8 package.
