Achieves lowest insertion loss and smallest size in the industry by using new generation TaRF5 process
TOKYO - Tuesday, October 8th 2013 [ME NewsWire]
(BUSINESS WIRE)-- Toshiba Corporation (TOKYO:6502) today announced that it has developed an SP10T[1] RF antenna switch with a MIPI® RFFE[2] interface that achieves the lowest insertion loss[3] and smallest size in the industry[4] for the smartphone market. Sample shipment starts from today.
The new product uses "TaRF5”, a new generation TarfSOI™ (Toshiba advanced RF SOI)[5] process using silicon on insulator (SOI) technology[6]. By using the TaRF5 process, the new samples achieve a 25% improvement in insertion loss (f=2.7GHz) and a 40% size reduction against products using the TaRF3 process. These improvements can lead to longer battery operating time and smaller mounting space, which can also contribute to smaller sizes for products in which they are used.
Since developing the SOI-CMOS process for smartphone RF antenna switches in 2009, Toshiba has continually developed new generation processes and devices offering improved performance. With LTE now being implemented worldwide, and LTE-Advanced[7] expected to follow, requirements for RF antenna switches are leaning towards multi-port and complex functions. To meet those market demands, Toshiba plans to continue to develop products with low insertion loss and smaller sizes.
