NJG1690MD7 HIGH ISOLATION X-SPDT (DP4T) SWITCH GaAs MMIC I GENERAL DESCRIPTION The NJG1690MD7 is a GaAs X (cross)-SPDT(DP4T) switch MMIC for switching of balanced (differential) dual band filters. It features low insertion loss and very high isolation for balanced signal input which makes it much suited for balanced filter switching. The ESD protection circuit are integrated in the IC to achieve high ESD tolerance. The ultra-small and ultra-thin EQFN14-D7 package is adopted. I PACKAGE OUTLINE NJG1690MD7 *) X-SPDT is a paired SPDT switch controlled synchronously. The X-SPDT includes two SPDT switches whose RF lines have a crossing inside the chip.

[2] For good RF performance, through-holes for GND should be placed close to the GND pin 6 and pin 13. One of the ways to do this is to place a via-hole at the TAB pad under this IC. ■ RECOMMENDED FOOTPRINT PATTERN (EQFN14-D7 PACKAGE Reference) :Land :Mask (Open area) *Metal mask thickness : 100µm PKG: 1.6mm x 1.6mm Pin pitch: 0.4mm :Resist(Open area) Detail A - 11 - NJG1690MD7 ■ PACKAGE OUTLINE (EQFN14-D7) Units Board Terminal treat Molding material Weight 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.
