His expertise and vision continue to push the boundaries of what's possible in the realm of telecommunications.

Latest Patents

Among his recent inventions, two standout patents include a Decomposer and Amplifier—specifically a quadrature out-phasing system. This system consists of a first baseband signal modifier aligned to receive a first baseband signal component and generate two constant envelope RF carriers. Additionally, a second baseband signal modifier processes a second baseband signal component to produce two more RF carriers. The assembly further encapsulates signal combiners that generate RF PWM signals by combining these carriers.

Another notable patent from Vromans is the Quad LINC transmitter featuring switchable Chireix amplifiers. This transmitter incorporates two Chireix compensation circuits, each with two inputs and outputs. The innovation allows constant envelope input signals to be directed to either the first or second Chireix amplifier unit based on the phase of the input signals, thereby ensuring optimal signal matching thanks to cross-coupled outputs to an inductive load.
