Longer battery life in 5G smartphones with Infineon's new antenna tuners

The number of connected devices is growing rapidly. At the same time, customers expect an ever-better user experience in terms of product design and functionality. This poses a major challenge for RF engineers, as antenna design complexity is also constantly increasing due to new features, performance requirements and innovative form factors. In particular, the introduction of 5G brings additional challenges as even more frequency bands need to be covered in a limited space. All these factors potentially impact antenna performance.

To support RF engineers, Infineon Technologies AG is expanding its portfolio of smallest, ready-to-use antenna tuners. Following the market launch of the BGSA147ML10, Infineon is now further expanding its range of antenna tuners with new antenna tuning switches. These devices are suitable for Sub-7.2GHz New Radio (NR) applications, supporting both 4G and 5G in smartphones, notebooks, wearables, VR headsets, smart home and other cellular applications.

Antenna tuners BGSA144ML10, BGSA400ML10 and BGSA403ML10 are available in the 1.1 x 1.5mm ² TSLP 10-pin package. BGSA14M2N10, on the other hand, comes in the 0.95 x 1.3mm ² TSNP 10-pin package with 350 μm pad pitch.
