Abstract: A method for facilitating the impedance matching of radiofrequency circuits, notably transmission circuits using a power amplifier connected to a load which may include an antenna. A signal is produced for measuring the temperature resulting from the operation of the output amplifier stage, by a temperature sensor positioned in the immediate vicinity of this stage, the measuring signal is used to control a circuit for controlling the variable impedances of a matching network positioned between the amplifier and the load, and values which seek to minimize the sensed temperature are applied to these variable impedances values. An abnormal heating of the amplifier is an indication of an impedance mismatch that must be corrected to restore a minimum temperature.

Abstract: In one embodiment, a circuit couples an integrated circuit to a powerline and protects the integrated circuit from overvoltage noise. In one example, the integrated circuit comprises a two-port differential transceiver. Respective Schottky diodes couple the ports to a power supply and reference, so one diode for each port conducts current in forward bias if an applied voltage exceeds a respective voltage reference plus the forward voltage of that diode. A respective end of a first transformer winding feeds each input port. Respective ends of a second transformer winding couple to capacitors that couple with the powerline. Back-to-back zener diodes are connected between the ends of the second winding. A zener diode with a breakdown voltage set based on the power supply voltage plus a margin is coupled between the power supply and ground so that the power supply voltage does not exceed a desired value plus the margin.
