A new window will open
RF switches are suitable for use as RF front-end antenna switches in smartphones. Toshiba's RF switches are the ideal solution for RF front-end module applications compliant with LTE, which is being adopted worldwide, as well as with LTE Advanced, which will be commercially deployed shortly.
As a successor to the Toshiba-original TarfSOI™ (Toshiba advanced RF SOI) process, Toshiba has developed the new TaRF5 process, which provides the world's smallest*2 insertion loss and a small form factor. RF switches fabricated with the TaRF5 process deliver approximately 25% lower insertion loss (at 2.7 GHz) and approximately 40% size reduction (for SP10T), compared to the comparable devices fabricated with the TaRF3 process.
Note 1: TarfSOI is a trademark of Toshiba Corporation.
Note 2: As of June 28, 2013 (according to a Toshiba survey of the RF antenna switch market)
* All the above devices are housed in a Chip BGA package.
