Title:Low-noise amplifier (LNA) and Power amplifier (PA) for Radio-Frequency (RF) System-on–Chip (SoC) Applications on Silicon on Sapphire (SOS) Substrates
Abstract:This proposal explores the feasibility of a communication system based on the modulation of a magnetic field. The principle of mutual induction states that the voltage induced by mutual induction in one inductor is always proportional to the rate of current change in the other inductor. If one inductor is in the transmitter, and the other inductor is in the receiver, the induced voltage in the receiving inductor shall follow the modulation of the current in the transmitting inductor.

Title:Low-noise amplifier (LNA) and Power amplifier (PA) for Radio-Frequency (RF) System-on–Chip (SoC) Applications on Silicon on Sapphire (SOS) Substrates
Abstract:This Phase I SBIR research project explores the feasibility of a portable long-range magnetic field communication that can transmit and receive a minimum data rate of 10kbps at a distance of 1 km without use of repeaters. Magnetic communications can function through earth, concrete and buildings. A digital modulation scheme is proposed for both voice and data. In the voice transmission mode a VOX circuit can be employed to conserve battery power. Advantages by using digital modulations include potential to MUX and DEMUX voice and data, use of error correction codes for error free communications, potential use of data compression algorithms, and reduced bandwidth. The novel receiver approach eliminates out-of-band noise with an extremely sharp filter, and the signal is extracted from the in-band noise by an auto-correlator receiver. The auto correlation function offers some other unique benefits such as making the system more LPI/LPD. The portable transmit antenna is envisioned as a tuned magnetic loop antenna. If the pulses were filtered to create Gaussian or sinc pulses, bandwidth reductions would accrue which would reduce antenna bandwidth requirements.

Title:Magnetically-coupled Integrated Secure Transceiver - MIST
Abstract:In this SBIR program, Structured Materials Industries, Inc. www.structuredmaterials.com (SMI) will develop tunable RF capacitors with ultra-low series resistance. The tunable capacitors will be based on the tunable dielectric material barium strontium titanate - BaxSr1-xTiO3 (commonly referred to as BST). Presently, two factors limit implementation of tunable BST capacitors in RF systems; 1) poor temperature stability and 2) high series resistance. SMI is presently leading a team to solve the temperature stability problem for BST capacitors. In this proposed SBIR program, we will solve the series resistance problem and remove the last remaining obstacle for commercial implementation of tunable BST capacitors in military and commercial products. In Phase I, SMI will implement a 4-part strategy to reduce series resistance for tunable BST capacitors; including optimization of the capacitor geometry, optimization of the metallization, optimization of the interface between the metal and the tunable dielectric, and optimization of the tunable dielectric composition profile. In Phase II, we will optimize the manufacturing processes and the tooling, and demonstrate a pathway to low-cost, high-volume production. We will also produce optimized BST capacitors in Phase II, and demonstrate performance and reliability far superior to any commercially available alternative.

Title:Magnetoelectric Transducer Array for Long Range Near-field Magnetic Communication
Abstract:In this Small Business Innovation Research Phase I project, Amsen Technologies is teamed with the Center for Advanced Materials (CAM) of University of Houston to develop a process to fabricate BST thin film capacitors with reduced series resistance through an innovative interface optimization strategy. The overall objective of the present innovation is to grow epitaxial or highly oriented BST thin film on epitaxial Pt electrodes. Experimentally, three steps need to go in sequence to make the BST-on-Pt structure, both E-beam evaporation and pulsed laser deposition (PLD) will be used in the process. The Phase I effort will be aimed at establishing the proof-of-concept that the new process to fabricate BST thin film capacitors with reduced series resistance can be developed. In Phase II, we will be devoted to the optimization of the technology.
