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.
