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.

I PRECAUTIONS
[1] No DC block capacitors are required for RF ports unless DC is biased externally. When the other device is
biased at certain voltage and connected to the NJG1684ME2, a DC block capacitor is required between
the device and the switch IC. This is because the each RF port of NJG1684ME2 is biased at 0 V (GND).
[2] 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.
[3] 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.
