HIGH POWER SPDT SWITCH GaAs MMIC
I GENERAL DESCRIPTION I
II
I PACKAGE OUTLINE
The NJG1681MD7 is a GaAs SPDT switch MMIC suitable for
LTE/UMTS/CDMA/GSM applications.
The NJG1681MD7 features very low insertion loss, high isolation
and excellent linearity performance down to 1.8V control voltage at
high frequency up to 6GHz. In addition, this switch is able to handle
high power signals.
The NJG1681MD7 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 EQFN14-D7 package is adopted.
I APPLICATIONS
LTE, UMTS, CDMA, GSM applications
IEEE802.11p application
Antenna switching, bands switching, post PA switching applications

(TOP VIEW)
Note: No DC blocking capacitors are required on all RF ports, unless DC is biased externally.
* The Inductor L1 is required for enhancing ESD protection level.
The inductor L1 is recommended in order to keep the DC bias level of each RF port at 0 V level tightly.

I PRECAUTIONS
[1] No DC blocking capacitors are required at each RF port normally. When the other device is biased at
certain voltage and connected to the NJG1681MD7, a DC block capacitor is required between the device
and the switch IC. This is because the each RF port of NJG1681MD7 is biased at 0 V (GND).
[2] For avoiding the degradation of RF performance, the bypass capacitor (C1) should be placed as close as
possible to VDD terminal
[3] For good RF performance, all GND terminals are must be connected to PCB ground plane of substrate, and
through - holes for GND should be placed the IC near.
