CXG1176UR
High Power DPDT Switch with Logic Control
Description
This IC can be used in wireless communication
systems, for example, W-CDMA handsets.
The IC has on-chip logic for operation with 2
12 pin UQFN (Plastic)
CMOS control inputs.
The Sony JPHEMT process is used for low insertion
loss and on-chip logic circuit.
Features
• Low insertion loss
• 2 CMOS compatible control line
• Small package size: 12-pin UQFN
Applications
• Antenna switch for cellular handsets
• Dual-Band W-CDMA
