NJG1683ME7 High Isolation X-SP3T (DP6T) SWITCH I GENERAL DESCRIPTION The NJG1683ME7 is a GaAs X (cross) - SP3T (DP6T) switch MMIC for switching of balanced (differential) triple band filters, upper pin compatible for NJG1655ME7. 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 circuits are integrated in the IC to achieve high ESD tolerance. The ultra-small and ultra-thin EQFN18-E7 package is adopted. I PACKAGE OUTLINE NJG1683ME7 *) The X-SP3T is a paired SP3T switch that features two identical SP3T switches being integrated into one chip. The two SP3T switches are controlled synchronously, and their respective RF lines cross each other on the chip.

0.10mm) Pin Note2: The ground plane and the through-holes under Tab, as shown in the picture, are not necessities. There is no problem in deleting them in the practical PCB design, though in such case beware that the GND terminals (pin 1, 2, 8, 9 and 10 as for this particular design shown in the picture) still need through-holes being located in their vicinities. PRECAUTIONS [1] The DC current at RF ports must be equal to zero, which can be achieved with DC blocking capacitors (C1~C8). (However, in case there is no possibility that DC current flows, the DC blocking capacitors are unnecessary, e.g. the RF signals are fed by SAW filters that block DC current by nature, etc.) [2] To reduce stripline influence on RF characteristics, please locate the bypass capacitor (C9) close to VDD terminal. [3] For good isolation, the GND terminals must be connected to the PCB ground plane of substrate, and the through-holes connecting the backside ground plane should be placed near by the pin connection. - 11 - NJG1683ME7 I RECOMMENDED FOOTPRINT PATTERN (EQFN18-E7 PACKAGE REFERENCE) : Land : Mask (Open area) *Metal mask thickness: 100um : Resist (Open area) PKG : 2.0mm x 2.0mm Pin pitch : 0.4mm Detail A - 12 - NJG1683ME7 I PACKAGE OUTLINE (EQFN18-E7) Terminal Treat Board Molding Material Weight :SnBi :Copper :Epoxy resin :5.0mg Unit :mm 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.
