MB/HB SP12T Antenna Switch Module with MIPI I/F
CXM3656K
Description
The CXM3656K is a SP12T antenna switch module for use in a multimode (GSM/UMTS/CDMA/LTE) carrier
aggregation (CA) handset or embedded data card application.
The CXM3656K consist of an SP12T switch with ten (mid band and high band [MB and HB]) TRx ports and one
Tx port with integrated GSM HB LPF and another Tx port supporting GSM HB power and linearity but without
integrated LPF.
The CXM3656K use MIPI RFFE interface for all device commands and controls.
The Sony GaAs junction gate pHEMT (JPHEMT) MMIC process is used for low insertion loss.
The device has low BOM with no DC blocking Capacitor.
Features

Low Insertion Loss:
0.80dB (Typ.) TRx1-4 (2.7GHz)

Low Voltage Operation:
Vdd=2.5V

Supports CMOS control for serial interface

No DC Blocking Capacitors except external DC bias

Small Package Size:

Lead-Free and RoHS Compliant
LTCC-24P PKG (2.4mm x 3.2mm x 1.00mm Max.)
Structure
GaAs Junction Gate pHEMT (JPHEMT) MMIC Switch, CMOS Decoder
This IC is ESD sensitive device. Special handling precautions are required.
