1 Overview
1.1 Objective
This document describes the design process for integration TigoBridge SOM on top of a Carrier
board.
The process of integrating TigoBridge SOM includes the following steps:
1. Mechanical design:
a. Placing the BTB connectors in the correct positions.
b. Considering TigoBridge SOM dimension for placing it inside the host enclosure.
c. Connecting and routing of the antenna cable.
2. Electrical design:
a. TigoBridge SOM pin out description and connectivity
b. Application and implementation
1.2 TigoBridge SOM Integration folder content
Provided with this guide please find the following files:
1. “TigoBridge.STEP” SOM STEP file
2. Example data sheet for UFL to SMA cable: “IPEX_MHF_Connector.pdf”
3. Example data sheet for a whip antenna: “W24-SSMA.pdf”
4. DXF file of “TigoBridgeMatingBoard.DXF” pcb (for correct positioning of the BTB
connectors)
5. Mollex BTB connectors data sheet – “533531671.pdf”, “533532071.pdf”

2 Mechanical design
2.1 TigoBridge SOM dimensions
Please consider TigoBridge SOM dimension in your design:
 Height = 7mm
Figure 1: TigoBridge SOM height
 Length = 30mm
Figure 2: TigoBridge SOM length

 Width = 20mm
Figure 3: TigoBridge SOM width
Kindly implement TigoBridge SOM STEP file provided into your mechanical design, please
mind:
1. Location of the BTB connectors
2. Height constrains between TigoBridge SOM board to the host board
3. Location of the UFL connector for connecting the antenna and the height required for
physically connecting the UFL connector to the board
2.2 Antenna connection
After choosing the location of the SMA connector on the enclosure panel, one should design the
RF cable accordingly. Provided please find an example for UFL to SMA connection and an
example for a whip antenna.
Please take into consideration in your RF cable selection or design:
 The UFL connector should be connected manually and maintain a steady connection
 The RF cable UFL connectors adds height to the total PCB height
 The RF cable length should not be short so physical pressure will imply on the UFL
connection
 The RF cable should not be too long because unnecessary length adds to the cable
attenuation and degrade overall performance of the system
 The selection of the RF cable should match the frequency band in use and the impedance
requirement:
o Frequency band: 2.4-2.48 [GHz]
o Impedance: 50Ω

2.3 Placing the BTB connectors
For placing the Molex BTB connector in the exact correct location, please use
TigoBridgeMatingBoard DXF file as a reference for your design and place the connector exactly
as in the DXF file.
Figure 4: Matching board BTB connectors location
All other information in the DXF file, but the Molex connectors, should be ignored.
