Success in boosting sensitivity by tenfold over conventional
receiver chips will enable 240GHz millimeter-band, high-capacity reception for
smartphones and other devices
Fujitsu Limited and Fujitsu Laboratories Ltd. today
announced development of a high-sensitivity receiver chip that will pave the
way to high-capacity, gigabit-capable wireless devices operating at 240GHz in
the millimeter-wave frequency band.
The 240GHz band is a frequency range over 100 times wider
than that used by typical mobile devices today (0.8–2GHz), which should enable
a 100-fold increase in communications capacity. To achieve such an increase,
however, requires amplifiers with high amplification ratios that can receive
signals that have become very faint when transmitted through the air.
