Frequency-agile monolithic Ka-band filter

Future multiband communications systems demand frequency agile filters. While such devices are available at millimeter wave, they suffer from large size and high cost, among others. For this STTR Phase II effort, nGimat, working with Georgia Tech, will develop a miniaturized, low-loss, tunable Ka-band bandpass filter using its low-cost tunable thin film technology. In Phase I, nGimat has successfully demonstrated the feasibility of several filter designs using the tunable dielectric thin films, which showed adequate tuning and acceptable loss. New materials were also developed. In Phase II, a fully packaged prototype filter, deliverable to Army and industrial partners, will be developed through comprehensive design, optimization, and test efforts. A cost model will be provided and path forward for large scale manufacturability will be discussed.
