HTC NE11 Wireless Earphones RF Test Report
Report No.: PTC25032714608E-FC01
14 Antenna Requirement
14.1 Test Standard and Requirement
Test Standard: FCC Part15 Section 15.203 /247(c)
1) 15.203 requirement: An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator, the manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited.
2) 15.247(c)(1)(i) requirement: Systems operating in the 2400-2483.5 MHz band that is used exclusively for fixed. Point-to-point operations may employ transmitting antennas with directional gain greater than 6dBi provided the maximum conducted output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna exceeds 6 dBi.
14.2 Antenna Connected Construction
The antenna is a Ceramic antenna which is permanently attached. The best-case gain of the antenna is 1.7 dBi. It complies with the standard requirement.
15 Appendix I -- Test Setup Photograph
This section provides visual documentation of the test setups used for evaluating the HTC Wireless Earphones.
Conducted Emission Setup
A photograph shows the equipment arranged for conducted emission testing, including a spectrum analyzer and associated cabling.
Radiated Emissions Setup (30 MHz - 1 GHz)
A photograph depicts an anechoic chamber with a turntable and antenna setup, characteristic of radiated emissions testing in this frequency range.
Radiated Emissions Setup (Above 1 GHz)
A photograph shows an anechoic chamber with the Device Under Test (DUT) placed on a table, surrounded by antennas for testing emissions above 1 GHz.
16 Appendix II -- EUT Photograph
This section presents photographs of the Equipment Under Test (EUT), the HTC Wireless Earphones, and its internal components.
External Views
Multiple images display the HTC Wireless Earphones from various angles, highlighting the product design and the "HTC" branding. Measurements are indicated by rulers in centimeters.
Internal Components
Photographs reveal the internal circuitry of the earphones, including the main printed circuit board (PCB) with components such as a crystal oscillator (24.000 MHz), integrated circuits, and connectors. The battery pack, identified as "301012, 40mAh", is also shown.
The PCB is marked with model numbers such as "LDN-869-V1.0" and "BP20124-7204".
Spectrum Analyzer Test Results Summary
The report includes spectrum analyzer results for various test configurations of the HTC Wireless Earphones, covering Bluetooth modes (DH5, 2DH5, 3DH5) at frequencies 2402 MHz, 2441 MHz, and 2480 MHz. Tests included measurements across different frequency ranges (30 MHz - 1000 MHz, 1000 MHz - 26500 MHz) and reference checks. All configurations reported a "PASS" status.
