CXM3559ER [DP10T Antenna Switch for GSM/UMTS/LTE Multi-mode Phone ]

>>Description

The CXM3559ER is a SP9T antenna switch module for GSM/UMTS Dual-mode handset.
The CXM3559ER has a built-in dual low pass filter and a +1.8 V CMOS compatible Decoder.
The Sony GaAs junction gate pHEMT (JPHEMT) MMIC process is used for low insertion loss and linearity. The device has low BOM with no DC blocking capacitor.

>>Applications

Quad band GSM and triple band UMTS or CDMA dual-mode handset

>>Features

Low Insertion Loss:
0.90 dB (Typ.) On Tx1 (GSM Low band Tx)
0.75 dB (Typ.) On Tx2 (GSM High band Tx)
High attenuation:
28 dB (Min.) On Tx1 path @1648-1830 MHz
25 dB (Min.) On Tx2 path @3420-3820 MHz
RXs paths are changeable for band assignment
Low voltage operation: VDD = +2.5 V
No DC blocking capacitors (Small device footprint)
Small package size: VQFN-26P (3.0 mm x 3.8 mm x 0.8 mm Typ.)
Lead-free and RoHS compliant
