One of his latest patents is a modem for telecommunication systems with a reflection amplifier function. This modem is designed to be included in a badge or mobile station, facilitating data exchange via microwaves with a fixed station or beacon. The modem incorporates at least one transistor that functions as a detector during reception or as an amplifier for the transmission of a reflection signal, depending on the applied gate bias voltages and resulting drain currents. The switching between transmission and reception is managed by transistors that control loads and currents on an amplifier transistor, utilizing amplitude or phase modulation. This modem is particularly applicable in short-distance telecommunication systems. Another patent involves a circuit aimed at increasing the information bit rate in a microwave data exchange system between a fixed station and a mobile station or portable badge. In standby mode, the information bit rate is constrained by the low power consumption of the badge and the high output impedance of the modem. To enhance the information bit rate, the processing circuit associated with the modem sends an activation signal to lower its output impedance, employing transistors to
