X-SP4T SWITCH GaAs MMIC
GENERAL DESCRIPTION PACKAGE OUTLINE
The NJG1663K44 is a X (Cross) -SP4T* switch GaAs MMIC, which is
suitable for switching of balanced bandpass filters. The NJG1663K44
features very low phase error between on-state paths, low insertion loss,
low control voltage and wide frequency coverage. The
ESD protection
circuits are integrated in the IC to achieve high ESD tolerance.
The very small
and very thin QFN16-44 package is adopted.
*) X-SP4T is a paired SP4T switc h controlled synchronously. The X-SP4T includes two
SP4T switches whose RF lines have crossi ngs inside the MMIC.
