This document provides a comprehensive specification sheet for the Bluetooth antenna used in the M9 Max device. Manufactured by Shenzhen Lenodell Technology Co., Ltd., the antenna is directly integrated onto the PCB board using a copper foil with tin spraying process. The copper foil has a thickness of 1OZ, and the board is made of FR-4 material with a thickness of 1.6mm.
The document details the antenna's physical shape, including a physical picture and dimension drawings, specifying key measurements in millimeters. It also outlines the antenna's parameters, such as operating frequency (between 2402 and 2500 MHz), VSWR, impedance, return loss, radiation pattern, gain, polarization, admitted power, and connector type.
Furthermore, the specification sheet includes an antenna gain detection report, specifying the spectrum detector used, test conditions (temperature and humidity), and modulation type. It presents maximum gain values across a range of frequencies and provides 2D radiation patterns for various frequencies, offering a complete overview of the antenna's performance characteristics.
