NJG1663K44 X-SP4T SWITCH GaAs MMIC GENERAL DESCRIPTION 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. PACKAGE OUTLINE NJG1663K44 *) X-SP4T is a paired SP4T switch controlled synchronously. The X-SP4T includes two SP4T switches whose RF lines have crossings inside the MMIC.
