Description
The CXG1040TN is a DPDT (Dual Pole Dual
Throw) antenna switch MMIC used in Personal
Communication handsets such as PCS.
This IC is designed using the Sony’s GaAs J-FET
process and operates with CMOS input.
Features
• CMOS input control
• Insertion loss 0.5 dB (Typ.) at 2.0 GHz
• High isolation 25 dB (Typ.) at 2.0 GHz
• Small Package TSSOP-10pin
Applications
DPDT switch for digital cellular telephones such as
PCS handsets.

When using the CXG1040TN, the following external components should be used:
C1: This is used for signal line filtering 100 pF is recommended.
C2: This is used for RF De-coupling and must be used in all applications. 100 pF is recommended.
Rctl: This is used to give improved ESD performance.
Rrf: This resistor is used to stabilize the dc operating point at high power levels. A value of 220 kΩ is
recommended.
