Safety To achieve maximum safety while using the ULX, we suggest you adopt the following: If you have issues operating the device and troubleshooting does not work unplug the mouse, turn off the mouse and contact Finalmouse at [email protected]. Do not attempt to service or fix the mouse yourself at anytime. Do not take the mouse apart and do not attempt to operate it under abnormal current loads. Changes or modifications not expressly approved by Finalmouse LLC could void the user’s authority to operate the equipment. Replacing a battery with an incorrect type may remove protection, disposing of a battery in a fire or hot oven, or mechanically crushing or cutting a battery, may cause an explosion; keeping a battery in a high-temperature environment may cause an explosion, or leakage of flammable liquid or gas. A battery subjected to extremely low air pressure may cause an explosion or leakage of flammable liquid or gas. Keep the mouse away from liquid, humidity or moisture. Operate the mouse only within the temperature range of 0°C (32°F) to 40°C (104°F). If the temperature exceeds these specified ranges unplug the mouse and turn off the mouse to let the mouse and environment stabilize to the desired level.

v [0.1] — [05/20/2023] TECHNICAL REPORT: Finalmouse Mouse Antenna Report Prepared for: [Finalmouse] Prepared by: [Timothy Milam] Revision History REV Date Author Notes [0.1] [2023-05-20] [Timothy Milam] Antenna Report including tuning details and measurement data. [0.2] [2023-05-20] [Timothy Milam] Added data for changing the 3.0 nH shunt inductor on the Mouse to a 3.9 and retesting Finalmouse USB Dongle and Wireless Mouse Antenna Evaluation Report Finalmouse requested SMT tuning of the antennas in two products, 1) a USB dongle and 2) a wireless mouse. Due to FCC testing that will occur in a few days, there was no option offered for changing the antenna or any other layout. Later it was agreed to trim the Dongle antenna to see if it would tune better by the method. It did and radiated performance was better also. This trimmed version can be used during the FCC testing, since no copper tape was used, but the antenna radiator length will have to be the same for the final production board. 1 Test Equipment Used During this Antenna Feasibility Study Vector Network Analyzer “VNA” used was a CMT (Copper Mountain Technologies) Model #: S5085; a 50 Ohm, 2-Port, 2-Path, 9 kHz to 8.5 GHz, VNA S/N: 20107496. A CIA custom designed and built, 13 ft. x 9 ft. x 9 ft. anechoic antenna measurement chamber fully lined with Cumming Microwave “C-RAM SFC-18”, 18 in. deep pyramidal absorber and associated Cumming Microwave corner treatments and walkway absorber, see image below. Chamber source antenna is a RF Spin Model “QRH11”, Quad Ridged Horn Antenna, S/N: 200721Q11. Various Mini-Circuits “Flex Test” test cables and Precision Pasternack connectors and adapters were used in the closed system setup, as well as Teledyne “CCR33S80T” SPDT coaxial switches. CMT “TW-SMA” Torque Wrench (no S/N). CMT “S911T” Calibration Kit, SN: A266049. Omano 7x to 45 x trinocular microscope with Hayear Model: HY-5099 (no S/N) Industrial Inspection Camera and SW. CIA’s Anechoic Chamber 2 DUTs as Used for the VSWR and Radiated Pattern Measurements The Dongle and Mouse DUTs were supplied by Finalmouse and contained the latest hardware as it intended for FCC testing and ultimately production. Images of both units are shown below. Fully assembled Dongle as tested Fully assembled Mouse as tested 3 Measurement Data The antenna parameters measured were the VSWR and 6 principal radiation patterns (vertical and horizontal polarized data for each of the 3 principal planes of radiation). VSWR for the Dongle was measured on a wooden surface, the Mouse was also measured on a wooden surface, but had a mouse pad under it. Comparison VSWR was also supplied for the mouse with a hand on it as if it were being used normally (memory trace) and just sitting on the mouse pad with no human interaction; no discernable difference was seen. 3.1 Radiated Pattern Description Radiated Pattern Illustration Sphere NOTE: To minimize the number of illustrations a generic DUT is shown inside the pattern illustration sphere. NOTE: The source antenna is represented as pointing toward the DUT from the 0-degree data point as shown in the plots below. NOTE: Some labs have different interpretations of the spherical as well as the Cartesian coordinate systems than given below. They may point x, y, and z in different directions or define + or – signs differently on both coordinate systems. The descriptions below use the conventions that are used in the CIA lab. 3.1.1 Three Principal Planes of Radiation The red horizontal line, circumnavigating the sphere, represents the azimuth plane of radiation (cut), as labeled in the plots below. o Azimuth is also known as just the Phi plane or Phi at Theta = 90 o in a spherical coordinate system or the xy plane in the Cartesian coordinate system. The dark green vertical line represents the Elevation Front to Back (F/B) cut. o AKA the Theta plane at (that passes through) Phi = 0 o and 180 o in a spherical coordinate system or the yz plane in the Cartesian coordinate system. The dark blue vertical line represents the Elevation Left to Right (L/R) cut. o AKA the Theta cut at Phi = 90 o and 270 o or the xz plane in the Cartesian coordinate system. FYI: Some labs use Phi = +90 o and -90 o in a spherical coordinate system. When radiation pattern data is measured in both polarizations (V and H), the 6 resulting patterns are known as the 6 principal planes or “cuts”. The planes represented by the white lines are only measured when a full 3D data set is required. All principal and secondary planes or cuts are measured by positioning the DUT appropriately, for the plane to be measured and rotating the pedestal by 360 degrees, capturing VNA S21 (received signal amplitude) measurement data every 10 o . 4.1 Dongle Matched by only Trimming the PIFA Radiator Inside view with the 1.37 mm U.FL test cable attachment to the Dongle’s PCB CPW transmission line and trimmed PIFA 4.1.1 VSWR VSWR for the Dongle, with a 0 Ohm jumper in the L5 series position of the antenna matching circuit and the PIFA radiator trimmed by 3.85 mm. The Dongle tuned much better by the trimming method. 4 Finalmouse Antenna Data 4.1.2 Schematic with 0 Ohm Jumper Location Schematic markup for the Dongle antenna matching components. The red markup value (0 Ohm jumper) and a 3.85 mm shorter PIA radiator tuned the antenna as shown in the VSWR plot above. 4.1.3 PCBA After Trimming the Antenna Dongle PIFA radiator trimmed 3.85 mm. No SMT tuning was required. [redacted] 4.1.4 Radiated Patterns 4.2 Mouse with 3.9 nH Shunt Inductor No change to the DUT images. 4.2.1 VSWR VSWR of the mouse PIFA with a series 1.0 pF cap (muRata P/N: GJM1555C1H1R0BB01) in position R33 and a shunt 3.9 nH (TDK P/N: MLG1005S3N9CT000) inductor in position C15 Schematic markup for the Mouse antenna matching components. Red values were used to tune the antenna at the length supplied, per Finalmouse request on 05/20/2023. [ redacted ] 4.2.2 Radiated Patterns; The plot scale has been kept to match the previous Mouse…

Measurement are done on a normalized test site. The test antenna is oriented in the two polarizations (vertical and horizontal), and the product is rotated at 360° in the horizontal plane (See photo(s) for initial position of the EUT(0°)). If applicable the test antenna was raised and lowered through the specified range of height until a maximum signal level is detected. For portable equipements a research of maximum level is done on the 3 axes. Only the highest levels are recorded.
