Development of Electronically Tunable and Fixed Filters for TVWS and 5G Wireless Systems

TV Whitespace (TVWS) designates the inactive or unused space between TV channels actively used in UHF and VHF spectrum :470 MHz to 700 MHz. The TVWS band performs best in the most rural service areas. This is due to the characteristics of TVWS, and how it’s shared with powerful analog TV stations Such TV transmitters can have up to hundreds of kilowatts of transmit power creating strong interference. Due to spectrum sharing with these powerful analog TV stations the reliability of wireless communications in TVWS is affected. Tunable receive channel filters are needed to provide enough rejection to deal with the interfering signals. The purpose of this project is to develop an electronically tunable band-pass filter that can be inserted between the antenna and the receiver of a TVWS system. The industrial sponsor of this project is Redline Communication. The project will provide training to two PhD graduate students.
