SP9T Antenna Switch for GSM/UMTS Dual Mode
CXM3529XR
Description
The CXM3529XR is SP9T antenna switch for GSM/UMTS dual mode. This IC has a 1.8V CMOS decoder. The Sony GaAs junction gate pHEMT (JPHEMT) MMIC process is used for low insertion loss and high linearity. (Applications: Quad Bands GSM and Triple Bands UMTS)
Features
Low Insertion Loss: 0.30dB (Typ.) Tx1 (GSM Low Band Tx) 0.45dB (Typ.) Tx2 (GSM High Band Tx) 0.60dB (Typ.) TRx1 (UMTS Band I)
Low Voltage Operation:VDD = 2.5V No DC Blocking Capacitors required on RF ports Lead-Free and RoHS Compliant
Package
Small package: 24pin XQFN (2.2mm x 2.9mm x 0.4mm Max.)
Structure
GaAs Junction Gate pHEMT (JPHEMT) MMIC Switch, CMOS Decoder
This IC is ESD sensitive device. Special handling precautions are required.
