TOKYO-Monday, September
(BUSINESS WIRE)-- Toshiba Electronic Devices & Storage Corporation (TDSC) today announced
Continued growth in the Internet of Things requires high-speed communications in environments increasingly crowded with numerous wireless LAN devices. IEEE 802.11ax, the next-generation wireless LAN, will be four times faster than its predecessor, even in crowded environments. However,
TDSC has developed three new technologies for low voltage RF receivers.
The first is a variable linearity RF amplifier (RFAMP). Since signal amplitude is affected by power supply voltage, the linearity of RFAMPs decreases as voltage falls. Conventional RFAMP uses variable resistance to improve the linearity, but internal DC voltage and amplifier performance are also changed by adjusting the resistor value. In order to avoid these problems, Toshiba’s new RFAMP simultaneously employs two input paths: a high linearity path and an internal voltage adjustment path. The RFAMP can adjust linearity without any change in the internal DC voltage.
The second is a low noise frequency converter. A frequency converter switches a received RF signal into a
The third is a current adder OPAMP. The OPAMP amplifies the converted
Integrating these three technologies into a 5GHz wireless LAN receiver has allowed TDSC to secure the level of performance essential for next-generation wireless LAN.
TDSC will continue to develop the
