SONY CXG1198AEQ

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)

0.50dB (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)
Package

In this circuit, Rx2, Rx3 and Rx4 are used for GSM triple band receive path.
The Rx1 is not used in this example.
User can select these Rx paths suitably.
∗1 Inductor (56nH) is recommended on Ant port for ESD protection.
∗2 These capacitors are not mandatory.
∗3 Capacitors are required on all RF ports for DC blocking.
Recommended capacitance is as follows.
For 800 to 960MHz signal: 56pF
For 1700 to 2200MHz signal: 33pF
