NJG1672LK4
SP9T ANTENNA SWITCH GaAs MMIC
GENERAL DESCRIPTION
The NJG1672LK4 is a GaAs SP9T antenna switch IC for
GSM/TD-SCDMA multi-band handsets. The IC contains a MMIC
switch die with on-chip logic circuits and a LTCC substrate with
built-in three LPFs on GSM/TD-SCDMA transmit paths for
suppression of transmitter harmonics.
This switch IC features very low harmonics, low insertion loss,
high Isolation and small package size.
This IC has ESD protection devices to achieve excellent ESD
performance.
No DC Blocking capacitors are required for RF ports.
FEATURES
Built-in three LPFs
Low harmonics
Low insertion loss
Small package size

Since all RF ports are biased at GND voltage, no DC cut capacitors
are required on all RF ports.
When the RF port of the adjacent component is DC biased and
connected with the RF port of NJG1672LK4, DC cut capacitor is
required.

PRECAUTIONS
[1] For good RF performance, the ground terminals should be directly connected to the
ground patterns and the through-holes as close as possible by using relatively wide
pattern.
[2] Please connect exposed GND PADs (bottom side of IC) to PCB GND using through
holes.
