Title: Power supply and method of operating a power amplifier
Inventor: JAKUB KORCZYC
IPC: H04W52/02
Filed: 2018-11-14
Abstract: A method of operating a power amplifier supplying power to an antenna includes first and second modes of operation (Fig.5). In the first operating mode switched power is supplied to the amplifier 107 using driver circuit 210 and one or more switches 215 to switch the supply of power to the amplifier on and off periodically. In the second mode of operation the power amplifier is calibrated by supplying power to the amplifier using the same driver circuit and switches for a pulse duration longer than the on/off period of the first mode. Optionally calibration includes measuring the amplifier output current at different voltages. In another aspect a power supply comprises one or more switches (Fig.3, 301, 302) and a driver circuit arranged to control the switches to supply switched power from a power source 220 to an output 225 of the power supply. Driver circuit inputs 231, 232 receive a first periodic switching signal 233 or a second switching signal 234 in respective first and second modes of operation corresponding to switching the supply of power to the output on and off periodically or supplying power to the output for a longer duration than the on/off period. One or more power supplies may be used in an RF front including one or more antennas 106 and amplifiers.
