STRAFT-P98L15 Antenna tuner for cellular application

Building high performance multimode / multiband mobile phones requires antennae capable of working over a wide frequency range. Such antennas are very difficult to fit within the mobile phone package, requiring the antenna designer to balance the antenna performance to the required form factor constraints.

This RAFT tuner has been specifically designed to tune the antenna impedance, by controlling the matching network located between the front end module output and the antenna, relaxing the constraints related to antenna design.

An optimized matching of the antenna to the platform can then be guaranteed during mobile phone operation, enabling TRP and TIS requirement to be met and optimized according to network operators stringent requirements.

The RAFT is dedicated to single antenna platforms.

Tuners are designed to operate over wide frequency range to cover multimode / multiband mobile phones.

Thanks to the associated control IC (STHVDAC-303xF6) the RAFT antenna tuner module allows mobile handset RF performance to be tailored on a band-by-band basis
