Antenna Tuning Device Carrier Aggregation Features Down Link Carrier aggregation will come, need simultaneous TRx and Up Link to apply multi band . BTS Mobile Cases, Band combination of Carrier Aggregation LB MB HB 3~5GHz Wide-Rang Antenna are necessary e.g. 3CC 700-960M 1.5-2.1G Band 2.3-2.7G Band-A LB MB HB 1) Intra-band, Freq. Return contiguous loss 2) Intra-band, non-contiguous 3) Inter-band, non-contiguous Frequency

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