Mobile devices use multiple RF switches and LNAs in the receiver circuit, requiring reduced circuit size to reduce required board area.<\/p>\n<p>Current LNAs typically use silicon-germanium-carbon (SiGe:C) bipolar transistors, making it difficult to integrate LNAs and RF switches fabricated with different processes on the same chip.<\/p>\n<p>The new TaRF10 process can integrate LNAs, control circuits and RF switches on a single chip, as it is highly compatible with RF switches based on the TaRF8 and TaRF9 processes \u2013 both of which have outstanding RF characteristics.<\/p>\n<p>TaRF9 realises lower insertion loss and signal distortion than TaRF8. Toshiba now plans to bring to market LNAs with integrated RF switches.
