CXG1040TN
High Isolation DPDT Switch
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. Structure GaAs J-FET MMIC 10 pin TSSOP (Plastic)
Absolute Maximum Ratings (Ta=25 C) * Supply voltage VDD 7 V * Control voltage Vctl 5 V * Input power Pin 25 dBm * Operating temperature Topr -35 to +85 C * Storage temperature Tstg -65 to +150 C
GaAs MMICs are ESD sensitive devices. Special handling precautions are required.

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 k is recommended.
