Description
The CXG1039TN is a high isolation absorptive
SPDT (Single Pole Dual Throw) switch MMIC used
in PCS handsets.
This IC is designed using the Sony’s GaAs J-FET
process and operates with CMOS input.
Features
• Absorptive type
• CMOS input control
• Low insertion loss 0.8 dB (Typ.) at 2.0 GHz
• High isolation 50 dB (Typ.) at 2.0 GHz
• Small Package TSSOP-10pin
Applications
High isolation switch for digital cellular telephones
such as PCS handsets.

When using the CXG1039TN, 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 100 kΩ is
recommended.
