There are many commercial markets for high-Q tunable filters and high-efficiency charge pumps. Electronics for personal wireless communications and industrial automation are becoming increasingly congested requiring co-existence of hardware that operate at multiple frequency bands. Military and Civil Aviation systems always required use of multiple frequencies and the new push to reduce footprint present great challenges. All these requirements can only be effectively managed by efficient tunable filter technology.
NASA has invested in S-Band wireless communication with software defined radio (SDR) and smart antennas. One of the critical technology gaps in implementation and rollout of the SDR is the tunable filters and inefficient offering of the current state-of-the-art. The proposed work closes this gap by innovative tuning mechanisms that include low-power low-ripple charge pumps.
