NJG1655ME7 X-SP3T(DP6T) SWITCH GaAs MMIC I GENERAL DESCRIPTION The NJG1655ME7 is a GaAs X (cross) - SP3T*(DP6T) switch MMIC, which is designed for switching of balanced signals. The NJG1655ME7 features very low phase error between on-state paths, low insertion loss, low control voltage and wide frequency coverage. The ESD protection circuit are integrated in the IC to achieve high ESD tolerance. The NJG1655ME7 is available in a very small, lead-free, halogen-free, 2.0mm x 2.0mm x 0.397 mm, 18-pin EQFN18-E7 package. I PACKAGE OUTLINE NJG1655ME7 *) X-SP3T is a paired SP3T switch controlled synchronously. The X-SP3T includes two SP3T switches whose RF lines have a crossing inside the chip.
