SP9T ANTENNA SWITCH GaAs MMIC
GENERAL DESCRIPTION
The NJG1656LK4 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 performances.
