Block Diagram

Recommended Usage Schematics

General Layout Guidelines

In order to achieve optimal RF performance, the following steps should be followed:

1. Use a 500 impedance controlled trace from the antenna pin (38) and the antenna connection.
2. Use a solid ground plane under the RF trace and the module.
3. Ensure the ground fill is heavily stitched with visa round the RF traces.
4. Keep all power supply and digital signals away from the RF traces.
5. If an impedance matching circuit is needed, ensure that no RF stubs are created.
6. Keep the RF path short, smooth and near. Use large radius bends, never 90 degree bends.
7. Choose a pc stickup so the RF trace width is close to the width of the matching component pads. This will minimize any impedance mismatch.
8. Do not use thermals on RF traces because of their high loss.

Power Management

Module power is derived from a 3.0 to 3.6V supply provided on pin VBAT. A 3.3V supply is provided on pin VDD_FEM to power the on-board ultra-long-range PA.
VDDIO sets the 10 voltage of the MM61 OB and should be connected to the same power supply as the host MCU.

Digital Interfaces

All unused digital 10 pins must be pulled up or down to ensure they do not float. Failure to do so, will result in a higher leakage current on the VDDIO supply.

Please refer to the MM6108 chip datasheets for a description of the supported peripheral interfaces.

Test Modes

This device uses various test mode programs for test set up which operate separate from production firmware. Host integrators should contact the grantee for assistance with test modes needed for module/host compliance test requirements.

Additional testing, Part 15 Subpart B disclaimer

The modular transmitter is only FCC authorized for the specific rule parts (i.e. FCC transmitter rules) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification.

The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.

EMI Considerations

Note that a host manufacture is recommended to use KDB996369 D04 Module Integration Guide recommending as “best practice” RF design engineering testing and evaluation in case non-linear interactions generate additional non-compliant limits due to module placement to host components or properties.

For standalone mode, reference the guidance in KDB996369 D04 Module Integration Guide and for simultaneous mode; see KDB996369 D02 Module Q&A Question 12, which permits the host manufacturer to confirm compliance.

How to make changes

Only Grantees are permitted to make perm1ss1ve changes, if the module will be used differently than granted conditions, please contact us to ensure modifications will not affect compliance.

Antenna Trace Design

The modular transmitter is configured for monostatic operation, which requires only a single RF 1/0 pin for full duplex communication. The output must be routed to the antenna via 50 ohm microstrip or strip line on the OEM PCB. No coupling capacitor is required given that the RF pin is AC-coupled internally.

• Length: 15mm
• Width: 0.508mm
• Thickness: 1.6mm
• Type of trace : 1 /2oz
• Dielectric constant : 4.3
• Antenna connector : RP-SMA
  

The trace from Pin No. 38 to antenna connector on the OEM PCB must be maintained identical as the above specification with RP-sMA connector. Only trace designs approved with an original grant or through permissive change can be used by an OEM, any changes are deemed as antenna type change and should be reviewed to ensure compliance with the FCC and ISED requirements.

Verification must be conducted and the results shall not exceed below ranges to ensure identical antenna design is applied to subsequent integration and end product production.

Impedance 50 ohm +/- 10%
Max power is 21.SdBm (Average power)
VSWR absolute max s 10:1 (limit to avoid permanent damage)
VSWR recommended s 1.92:1 (limit to fulfill all regulatory requirements)

Test procedure of verification
