Latest Patents
Ellis's latest patents include a "Configurable Radio Frequency Attenuator" and a "Transformerless Power Over Ethernet System." The Configurable Radio Frequency Attenuator features RF attenuator circuitry that includes an RF attenuator and a control system. This system is designed to provide an attenuation response between an input node and an output node. The control system is coupled to the RF attenuator and is configured to adjust control signals based on the temperature of the circuitry or an externally applied test signal. This ensures that the attenuation response is substantially linear-in-dB, allowing for easy and quick testing of the RF attenuator's performance.
The Transformerless Power Over Ethernet System is another innovative creation by Ellis. In this system, a powered device (PD) is equipped with a PHY module and a media access controller (MAC). The PD connects to power sourcing equipment (PSE) via a cable, allowing it to communicate and receive power in accordance with the Power-over-Ethernet (PoE) standard. This design extracts a DC signal from the cable to power the PD without
