NJG1662MD7
X-SPDT SWITCH GaAs MMIC
! GENERAL DESCRIPTION
The NJG1662MD7 is a GaAs X (cross) - SPDT switch MMIC, which is
designed for switching of balanced dual band filters.
The NJG1662MD7 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 ultra-small and ultra-thin EQFN14-D7 package is adopted.
