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.
*) 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.

Diameter: φ= 0.2mm
I PRECAUTIONS
[1] For good RF performance, all GND terminals must be connected to PCB ground plane of substrate, and
via-holes for GND should be placed near the IC.
[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.
