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
