Sensor Maestros Revised: June 18, 2022 Page 3 of 3 Federal Communication Commission Interference Statement This equipment was 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 into 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. FCC Caution Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Important Note Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. Country Code selection feature to be disabled for products marketed to the US/CANADA. This device is intended only for OEM integrators under the following conditions: 1.The antenna must be installed such that 20 centimeters is maintained between the antenna and users, and 2.The transmitter module may not be co-located with any other transmitter or antenna, 3.For all products market in US, OEM must limit the operation channels in CH0 to CH39 for 2.4G band by supplied firmware programming tool. OEM shall not supply any tool or info to the end user regarding to Regulatory Domain change. If the conditions above are met, further transmitter test are not required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed. Important Note In the event that these conditions cannot be met (for example, certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator is responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization End Product Labeling This transmitter module is authorized only for use in a device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: Contains FCC ID: XXXX-XXXX Manual Information to the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory informati…

PCB Antenna Bandwidth One way of measuring the bandwidth after the antenna is implemented on a PCB and connected to a transmitter is to write test software that steps a carrier across the frequency band of interest. By using the maximum hold function on a spectrum analyzer, the variation in output power across frequency can easily be measured. Figure 9 shows how the output power varies on the IFA when the PCB is horizontally oriented and the receiving antenna has horizontal polarization. This measurement was not performed in an anechoic chamber, thus the graph shows only the relative variation for the given frequency band. Figure 9. Bandwidth of PCB Antenna 4.

Suchfiles are includedin CC2430DBreferencedesign[1]. The gerberfile is calledInverted_F_Antenna.spland the DXFfile is calledInverted_F_Antenna.dxf.If the antennais implementedon a PCBthat is widerthanthe antenna,avoidplacingcomponentsor havinga ground planecloseto the end pointsof the antenna.If the CADtool beinguseddoesnot supportimportinggerber or DXFfiles,see Figure1 and Table1. The antennaimpedanceis tunedto 50 ohmon the referenceboard.The impedancewill howeverbe affectedby differentsize and shapeof the groundplane,objectsin the antennanearfieldsuchas mechanicalassemblies(housing,batteries,etc.),PCBthickness,PCBmaterialand so on. It is therefore recommendedto add a pi-networkcloseto the antennafeedpointfor impedancematching.
