Huawei ME909u-521 Mini PCIe Module Features
Antenna efficiency is the ratio of the input power to the radiated or received power of an antenna. The radiated power of an antenna is always lower than the input power due to the following antenna losses: mengembalikan kerugian, material loss, and coupling loss. The efficiency of an antenna relates to its electrical dimensions. To be specific, the antenna efficiency increases with the electrical dimensions. Selain itu, the transmission cable from the antenna connector of PCIe Adapter to the antenna is also part of the antenna. The cable loss increases with the cable length and the frequency.
It is recommended that the cable loss is as low as possible, Misalnya, U.FL-LP-088 made by HRS. The following antenna efficiency (free space) is recommended for ME909u-521 Mini PCIe module to ensure high radio performance of the module: Efficiency of the primary antenna: ≥ 40% (below 960 MHz); ≥ 50% (lebih 1710 MHz) Efficiency of the diversity antenna: ≥ half of the efficiency of the primary antenna in receiving band Efficiency of the GPS antenna: ≥ 50% Selain itu, the efficiency should be tested with the transmission cable.
