Conclusion
- Antenna Tuning usage increase
- Integration vertically and horizontally
MIMO / CA makes Antenna configuration complex and its covering frequency
- wide. Both aperture and impedance Antenna Tuning devices are required.
Combining RF-FE function blocks into SOI single chip technology, Sony will be able to support future 5G requirement.
- Unique RF-SOI technology
With Sony’s in-house high power handling SOI, antenna tuning devices can reach superior performance and small size.
