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.

Note1:
The balanced mode isolation is a unique specification for isolation defined under the condition where
the X-SPDT switch is used in balanced mode operation as shown in application circuit2.
The NJG1690MD7 is designed so that the isolation in the balanced mode operation is much higher than
the isolation in the single-ended mode operation.
