NJG1672LK4

DataSheet.in 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 PIN CONFIGURATION (Top view) VC2 VC1 VC3 VC4 VC5 VC6 PACKAGE OUTLINE NJG1672LK4 Attenuation 35/32/30 dB typ. on GSM850/900 TX @2fo / 3fo / 4fo Attenuation 32/45 dB typ. on GSM1800/1900 TX @2fo / 3fo Attenuation 35 dB typ. on LCR TX @2fo / 3fo -78/-75dBc typ. on GSM850/900 TX @2fo / 3fo, Pin=+35dBm, VDD=2.7V -85dBc typ. on GSM1800/1900 TX @2fo / 3fo, Pin=+32dBm, VDD=2.7V -90/-95dBc typ. on LCR TX @2fo / 3fo, Pin=+26dBm, VDD=2.7V 1.0dB typ. on GSM850/900 TX @f=915MHz, Pin=35dBm, VDD=2.7V 0.9dB typ. on GSM1800/1900 TX @f=1910MHz, Pin=32dBm, VDD=2.7V 1.0dB typ. on LCR TX @f=2025MHz, Pin=26dBm, VDD=2.7V LCSP24-K4 (Package size: 3.8x3.8x0.9mm typ.)
