NJG1695ME7
High Isolation X-SP4T (DP8T) SWITCH
GENERAL DESCRIPTION
The NJG1695ME7 is a GaAs X (cross) - SP4T (DP8T) switch
MMIC for switching of balanced (differential) mode filters. It
features low insertion loss and very high isolation for balanced
signal input.
The ESD protection circuits are integrated in the IC to achieve
high ESD tolerance.
The ultra-small and ultra-thin EQFN18-E7 package is adopted.
PACKAGE OUTLINE
NJG1695ME7
*) The X-SP4T is a paired SP4T switch that features two identical SP4T switches being integrated into one chip. The two
SP4T switches are controlled synchronously, and their respective RF lines cross each other on the chip.
APPLICATIONS
Switching of balanced type filters (Quad band) application
Suitable for 3G and LTE application
FEATURES
Low operation voltage
Low control voltage
High isolation
(Balanced mode)

Through-hole (radius: 0.15mm)
Pin
Note2:
The ground plane and the through-holes under Tab, as shown
in the picture, are not necessities. There is no problem in
deleting them in the practical PCB design, though in such case
beware that the GND terminals (pin 10 and 14 as for this
particular design shown in the picture) still need through-holes
being located in their vicinities.
PRECAUTIONS
[1] The DC current at RF ports must be equal to zero, which can be achieved with DC blocking capacitors
(C1~C10).
(However, in case there is no possibility that DC current flows, the DC blocking capacitors are unnecessary, i.e.
the RF signals are fed by SAW filters that block DC current by nature, etc.)
[2] To reduce stripline influence on RF characteristics, please locate the bypass capacitor (C11) close to VDD
terminal.
[3] For good isolation, the GND terminals must be connected to the PCB ground plane of substrate, and the
through-holes connecting the backside ground plane should be placed near by the pin connection.
