Huawei Boosts Smartphone 4G Reliability and Performance with Lattice Semiconductor Tunable Antenna Solution
Huawei’s Kirin 930 smartphone platform achieves automatic 4G RF optimization with the smart antenna switching functionality of the Lattice iCE40 LM FPGA
- Lattice’s low latency tunable antenna controller allows Huawei’s Multi-Scenario Adaptive RF solution to automatically optimize 4G reception for various RF conditions.
- Lattice tunable antenna controller helps phone manufacturers achieve optimal reception quality when designing devices with metal exteriors.
- The iCE40 LM family delivers unsurpassed integration of important functions to enable designers of mobile consumer devices to implement compelling features where solution size, lowest power, and high volume pricing are of upmost importance.
The Signal+ technology in Huawei’s P8 uses the iCE40 LM FPGA to automatically optimize 4G reception for multiple RF conditions. The resulting antenna solution is 80 times faster than other options, providing reception quality that is 40 percent better than Huawei’s competitors in the poorly covered or congested RF environments frequently found in both high-density cities and rural areas with limited reception.
Huawei put considerable effort into designing the P8’s attractive one-piece aluminum body, and the Lattice tunable antenna controller helps it achieve optimal RF performance and overcome the inherent RF quality issues of metal casings. The iCE40 LM device performs as the bridge between the Kirin 930 application processor and tuner integrated circuit to minimize latency during an antenna switch, also saving system power.
“We designed the iCE40 LM to provide our partners ultimate flexibility
when designing consumer devices where space is at a premium,” said
