Time-Varying Transmission Line (TVTL) for Broadband, Low Noise, Nonreciprocal and Cross-Frequency RF Applications
July 13, 2021 @ 12:00 pm - 1:00 pm
Passive electromagnetic devices such as transmission lines, filters, and antennas are essential parts of a wireless system. They often dominate the system’s efficiency, bandwidth and noise performance. Traditional passives often operate in a time-invariant manner as they are built with materials and structures that have time-independent properties. They are subject to many well-known fundamental limits such as the reciprocity of the transmission line, limit of quality factors of passive filters, and limit of efficiency bandwidth products. The utilization of transistor-based active electronics may help to overcome some of these challenges but they oftentimes incur noise and power handling issues. Transmission lines, with time-varying impedances, can help to overcome many of those traditional limits in passives while offering a better noise and power handling performance compared to the active transistor-based circuits.
In this talk, multiple initiatives supported by NSF and DARPA will be reported on the development of a new class of electromagnetic devices based on time-varying transmission lines. These devices include circulators, mixers, filters, and correlators that may be constructed on integrated semiconductor platforms with time-dependent property enforced through parametric modulation or dynamic switching. Potential new applications such a full-duplex radios, tunable RF front-ends may be developed with this novel device concept.
