SP8T GSM/UMTS Dual Mode Antenna Switch
CXG1198AEQ
Description
The CXG1198AEQ is one of a range of low insertion loss, high power MMIC antenna switches for GSM/UMTS
dual-mode handset. The low insertion loss serves to extend the handset talk time.
The switch also contains on-chip logic circuits and built-in dual-LPF on GSM transmit paths for suppression of
transmitter harmonics. The dual-LPF is mounted on the lead frame and enables the reduction of component
count and simple PCB layout.
(Applications: GSM (Triple/Quad band)/UMTS (Dual band) dual-mode handset)
Features
‹ Low height (1.3mm Max.)
‹ Low insertion loss
0.90dB (Typ.) on Tx2 (1910MHz)
0.90dB (Typ.) on Rx4 (1990MHz)
0.50dB (Typ.) on TRx (1980MHz)
‹ Built-in dual-LPF
Att –30dB (Typ.) @2fo (Tx1)
Att –30dB (Typ.) @2fo (Tx2)
‹ 3 CMOS compatible control lines
‹ Small package size
28-pin LQFN (4.5mm × 3.2mm × 1.3mm)
