Title: The Innovations of Barry A. Syrett
Introduction
Barry A. Syrett is a notable inventor based in Ottawa, Canada. He has made significant contributions to the field of microwave technology, holding a total of 2 patents. His work primarily focuses on devices that enhance the performance of microwave radio transmission systems.
Latest Patents
One of Syrett's latest patents is a "Saw device tapped delay line and equalizer." This invention includes an apodized input IDT (inter-digital transducer) and multiple identical unapodized output IDTs. These output IDTs are designed to receive a surface acoustic wave (SAW) propagated from the input IDT after delays that increase by a specific amount. The design minimizes acoustic regeneration by utilizing a low impedance termination. This delay line is particularly useful in equalizers for microwave radio transmission systems, where the delay corresponds to the inverse of the symbol rate.
Another significant patent is for a "Dielectric resonator microwave bandpass filter." This invention features a printed circuit board supported within a cut-off waveguide. The design includes dielectric resonators and coupling loops, allowing for adjustments to achieve desired filter characteristics. The innovative use of tuning screws and microstrip transmission lines enhances the performance of the filter, making it suitable for various applications.
