Bluetooth SiP claims industry’s smallest form factor with antenna
The next generation of the Bluetooth Gecko module measures just 6.5 x 6.5mm, making it suitable for wearable devices. The BGM12x Blue Gecko, low energy, system in package (SiP) has been announced at electronica 2016 by Silicon Labs
The Bluetooth low energy SiP module has a built-in chip antenna, with a clearance area of 51mm2 to minimize PCB footprint in IoT and wearable designs, such as sports and fitness wearables, smartwatches, personal medical devices, wireless sensor nodes and other space-constrained, connected devices.
The SiP is based on the company’s Blue Gecko wireless SoC and features an ARM Cortex-M4 processor, high-output Bluetooth power amplifier, onboard antenna, external antenna options, oscillators and passives. It also includes a Bluetooth 4.2 stack and development tools. The company says that the level of integration frees developers from the complexities of RF system engineering, protocol decisions and antenna design, including those in low-cost, two-layer PCB designs.
A wireless software development kit can enable host or fully standalone operation through the Bluegiga BGScript scripting language or with the ANSI C programming language. The development kit has been upgraded to support new Bluetooth 4.2 features such as LE Secure Connections, LE Packet Extensions and LE dual-topology.
BGM12x modules are available with different transmit output power options, from 3dBm (BGM123) to 8dBm (BGM121).
