摘要
We discuss the development and potential applications of a microwave varactor technology using thin-film BST on inexpensive substrates. BST thin-films have been developed and optimized specifically for microwave integrated circuits, using both MOCVD-grown and RF magnetron-sputtered films. The material optimization efforts have concentrated on achieving high tunability and simultaneous low loss, and also developing robust electrode systems for circuit fabrication on silicon substrates. We present advances in monolithic microwave integrated capacitors and application to high performance and low-cost phase-shifters circuits. Efforts in frequency multiplication devices,will also be presented.
