Description
The CXG1068N is a high power antenna switch MMIC for use in Dualband GSM handsets. One antenna can be routed to either of the 2Tx or 2Rx ports. This IC is designed using the Sony’s GaAs J-FET process which enable the CXG1068N to be operated with low voltage.
Features
Low control voltage
Low insertion loss : 0.5 dB (Typ.) @900 MHz
0.65 dB (Typ.) @1.8 GHz
Small package :
SSOP-20pin (Pin interval of 0.5 mm pitch)
High power handling :
P1dB : 38 dBm (Typ.) 0/5 V control
Harmonics :
–31 dBm (Max.) Pin=35 dBm, 0/5 V control
Applications
Dualband GSM 900/GSM 1800 or GSM 900/GSM
1900 handsets.
Dualmode GSM/DECT handsets.
Structure
GaAs J-FET MMIC
SP4T Antenna Switch for GSM Dual band
20 pin SSOP (Plastic)
CXG1068N
GaAs MMICs are ESD sensitive devices. Special handling precautions are required.
