WiLink 1835模块天线参考设计WL1835MODCOM8B
The WiLink 1835 Module Antenna Design is a reference design that combines the functionalities of the WiLink 8 module with a built-in antenna on a single board, implementing the module in the way it’s been certified. Through this, customers are able to evaluate the performance of the module through embedded applications such as home automation and the Internet of Things that make use of both Wi-Fi and Bluetooth/Bluetooth Low Energy functionalities found on the WiLink 1835 module. This antenna design leverages the use of its certification by using the same antenna layout when the module was tested for certification, allowing customers to avoid repeated certification when creating their applications.
WiLink 1835模块天线参考设计主要特性:
• WLAN, Bluetooth, BLE on a module board
• 100-pin board card
• Dimension 76.0 mm(L) x 31.0 mm(W)
• WLAN 2.4 GHz SISO (20- and 40-MHz channels), 2.4-GHz MIMO (20-MHz channels)
• Support for BLE dual mode
• Seamless integration with TI Sitara and other application processors
• Design for TI AM335X general-purpose EVM
• WLAN and Bluetooth, BLE cores are software and hardware compatible with prior WL127x, WL128xand CC256x offerings, for smooth migration to device.
• Shared HCI transport for Bluetooth and BLE over UART and SDIO for WLAN.
• Wi-Fi / Bluetooth single antenna co-existence
• Built-in chip antenna
• Optional U.FL RF connector for external 2.4-GHz band antenna
• Direct connection to battery using external switching mode power supply supporting 4.8-V to 2.9-Voperation
• VIO in the 1.8-V domain
TI Module Key Benefits
