NJG1655ME7
X-SP3T SWITCH GaAs MMIC
I
GENERAL DESCRIPTION
The NJG1655ME7 is a GaAs X (cross) - SP3T* switch MMIC, which is
designed for switching of balanced signals. The NJG1655ME7 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 NJG1655ME7 is available in a very small, lead-free, halogen-free,
2.0mm x 2.0mm x 0.397 mm, 18-pin EQFN18-E7 package.
