| 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. *) X-SP4T is a paired SP4T switch controlled synchronously. The X-SP4T includes two SP4T switches whose RF lines have crossings inside the MMIC.

To reduce strip line influence on RF characteristics, please locate bypass capacitor (C11) close to VDD terminal. For good isolation, the GND terminal must be connected to the ground plane of substrate, and through-holes for GND should be placed near by the pin connection. - 11 - NJG1663K44 PACKAGE OUTLINE (QFN16-44) UNITS : mm SUBSTRATE MATERIAL : Copper TERMINAL FINISH : Sn-Bi plating MOLD MATERIAL : Epoxy resin (Halogen-free) WEIGHT : 7.7mg Cautions on using this product This product contains Gallium-Arsenide (GaAs), which is a harmful material. * Do NOT eat or put into mouth. * Do NOT dispose in fire or break up this product. * Do NOT chemically make gas or powder with this product. * To waste this product, please obey the relating law of your country.
