NJRC NJG1683ME7 High isolation x-sp3t (dp6t) switch Datasheet

NJG1683ME7
High Isolation X-SP3T (DP6T) SWITCH
I GENERAL DESCRIPTION
The NJG1683ME7 is a GaAs X (cross) - SP3T (DP6T) switch
MMIC for switching of balanced (differential) triple band filters,
upper pin compatible for NJG1655ME7. It features low insertion
loss and very high isolation for balanced signal input which makes
it much suited for balanced filter switching.
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.
I PACKAGE OUTLINE
NJG1683ME7
*) The X-SP3T is a paired SP3T switch that features two identical SP3T switches being integrated into one chip. The two
SP3T switches are controlled synchronously, and their respective RF lines cross each other on the chip.
I APPLICATIONS

PCB Pattern
Through-hole (radius: 0.10mm)
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 1, 2, 8, 9 and 10 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~C8).
(However, in case there is no possibility that DC current flows, the DC blocking capacitors are unnecessary, e.g.
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 (C9) 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.
