NJG1684ME2
HIGH POWER SP4T SWITCH GaAs MMIC
I
GENERAL DESCRIPTION
The NJG1684ME2 is a GaAs SP4T switch MMIC suitable for
LTE/UMTS/CDMA/GSM applications.
The NJG1684ME2 features very low insertion loss, high isolation
and excellent linearity performance down to 1.8V control voltage at
high frequency up to 2.7GHz. In addition, this switch is able to handle
high power signals.
The NJG1684ME2 has ESD protection devices to achieve excellent
ESD performances. No DC Blocking capacitors are required for all RF
ports
unless DC is biased externally.
And the ultra small & ultra thin
EQFN12-E2 package is adopted.
