SANYO supplies high-performance GaAs switching ICs that feature the industry's smallest package size and smallest number
of external components. SANYO discrete devices have been always leading the cell phone and mobile equipment markets.
SANYO is also developing devices that support the need for higher speeds and larger data capacities for image and video data
due to the inclusion of high pixel count cameras in this equipment.
