MJ-134 Module jig
MJ-134 is meant for component level troubleshooting.
The jig includes an RF interface for GSM, WCDMA and Bluetooth. In
addition, it has the following features:
• Provides mechanical interface with the engine module
• Provides galvanic connection to all needed test pads in module
For GSM850, GSM900, GSM1800, and GSM1900 bands, use XRS-6 RF
cable connected to right angle mount SMA connector on fixture. Use
losses for XRS-6 RF cable for correct attenuation values for accurate
testing and calibration. For GPS (1485 MHz) band, use CA-57RS with
XRS-6 RF cables. CA-57RS connects to jack X6201 located component
side top of module. Add losses for CA-57RS RF cable to losses for
XRS-6 RF cable for correct attenuation values for accurate testing
and calibration. For Bluetooth (2500 MHz) band, use instructions
for SB -6 (or JBT-9).
• Multiplexing between USB and FBUS media, controlled by Vusb
• MMC interface
• Duplicated SIM connector
• Connector for control unit
• Access for AV- and USB connectors

RJ-177 Soldering jig
RJ-177 is a soldering jig used for soldering and as a rework jig for the
engine module.
RJ-201 Rework jig
This jig is used in conjunction with the ST-65 stencil.
SA-130 RF coupler
The SA-130 coupler is for GSM RF Go/No Go testing. It interfaces with
the FS-52 and SS-62/CU-4 interface adapters. It allows RF function
testing in GSM bands of 850, 900, 1800 and 1900 MHz.
Note: SA-130 is not suitable for RF tuning.
