YCHIOT MAX3220-SMA UWB High Power RF Module Instructions

YCHIOT ® MAX3220 is a product based on YCHIOT® the ultra wideband (UWB) RF module of YCH3220 IC. It integrates all RF circuits, front-end amplifiers, power management, and clock circuits into one module, greatly simplifying the design time and cost for users. This module can be used for TOF or TDOA positioning systems, with a positioning error of less than 10cm and supporting data transmission rates of up to 6.8 Mbps. MAX3220 series module design complies with FiRa™ PHY and MAC specifications, compatible with other FiRa-compliant devices.™ Standard equipment enables mutual communication. There are currently two models of MAX3220 series modules, among which MAX3220-SMA is an SMA interface, and MAX3220-X antenna port that can be externally led out.

FCC STATEMENT

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

This device may not cause harmful interference, and

This device must accept any interference received, including interference that may cause undesired operation

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. The device has been evaluated to meetthe general RF exposure requirements. The device can be used in portable exposure conditions without restriction. UWB devices may not be employed for the operation of toys. Operation onboard an aircraft, a ship or a satellite is prohibited. The use of antennas mounted on outdoor structures, e.g., antennas mounted on the outside of a building or on a telephone pole, or any fixed outdoor infrastructure, is prohibited. Antennas may be mounted only on the handheld UWB device.

List of applicable FCC rules
The MAX3220 is a UWB Module. It operates on the 6.5GHz,8GHz and, therefore, is within U.S. FCC part 15.519, part 15.521 ,part 15.209 standard

Specific operational use conditions
The EUT is a UWB Module

Operation Frequency: 6.5GHz, 8GHz for UWB;
Modulation Type: BPM/BPSK
Number of Channels: 2 channels
Antenna Designation: Double copper tube Antenna
Antenna Gain: 2.72dBi

Summarise the specific operational use conditions
According to 15.519(a). Antennas mounted on outdoor structures, as antennas mounted on the outside of a building or on a telephone pole or any fixed outdoor infrastructure, are prohibited for use with this device. According to 15.521(a), UWB devices may not be employed for the operation of toys. Operation onboard aircraft. A ship or a satellite is prohibited. This module is limited to hand-held system hosts

Limited module procedure

Trace antenna designs
Not applicable The module has its own antenna, and doesn’t need a hosts printed board micro strip trace antenna etc.

RF exposure considerations
The device has been evaluated to meet the general RF exposure requirements. The device can be used in portable exposure conditions without restriction

Antenna used

Antenna Designation: Double copper tube Antenna
Antenna Gain: 2.72dBi,
Polarisation: Linear,

Impedance: 50 Ohms
Manufacturer: Dongguan Lianzhao Electronics CO.LTD

This device is intended only for host manufacturers under the following conditions:

The transmitter module may not be co-located with any other transmitter or antenna.
The module shall be only used with the Sleeve monopole antenna(s) that has been originally tested and certified with this module.
The antenna must be either permanently attached or employ a ‘unique’ antenna coupler

As long as the conditions above are met, further transmitter tests will not be required. However, the host manufacturer is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). After certification, adding a different antenna type requires a C2/3 PC.

Label and compliance information
Host product manufacturers need to provide a physical or e-label stating “Contains FCC ID: 2BLONMAX3220” with their finished product.

Information on test modes and additional testing requirements
The host manufacturer must perform tests of radiated & conducted emissions and spurious emissions, etc., according to the actual test modes for a stand-alone modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other transmitters in a host product. Only when all the test results of test modes comply with FCC requirements then the end product be sold legally.

Additional testing, Part 15 Subpart B disclaimer

The host product manufacturer is responsible for compliance with 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.

Note EMI Considerations

Note EMI Considerations: D04 Module Integration Guide has been considered as “best practice” for RF design engineering, testing, and evaluation of non-linear interactions, which can generate additional noncompliant limits due to module placement to host components or properties. For standalone mode, the D04 Module Integration Guide was referenced, and simultaneous mode was considered for the host product to confirm compliance.

How to make changes
Only the Grantee is permitted to make permissive changes.

FAQs

Q: What are the FCC regulations for the MAX3220 module?
