Development of Tunable RF Integrated Passive Devices

Wong, Ka Wai (University of Waterloo, 2017-05-11)

Radio frequency (RF) lumped elements are crucial building blocks for designing any type of passives circuits for RF front-end applications in mobile devices. In particular, high-quality (Q) factor lumped elements are ...
Tunable Filters and RF MEMS Variable Capacitors with Closed Loop Control

Zahirovic, Nino (University of Waterloo, 2012-01-23)

Multi-band and multi-mode radios are becoming prevalent and necessary in order to provide optimal data rates across a network with a diverse and spotty landscape of coverage areas (3G, HSPA, LTE, etc.). As the number of ...
Tunable Superconducting Microwave Filters

Laforge, Paul (University of Waterloo, 2010-08-20)

Adaptive microwave systems can benefit from the use of low loss tunable microwave filters. Realizing these tunable filters that show low loss characteristics can be very challenging. The proper materials, tuning elements, ...
