Abstract: The invention relates to a radio station for transmitting
signals. An antenna of a transmitter of the radio station is
matched to an output impedance of a power amplifier by
adding an impedance with a variable reactance. A processor
adjusts the variable reactance of the impedance according to
an output signal of the power amplifier. The impedance with
the variable reactance consists either of a plurality of
inductors and capacitors or of variable inductors and
capacitors or of a plurality of microstrip lines. The
processor calculates an optimum value for the variable
reactance according to a measurement of the output signal of
the power amplifier and stores those values for those
measured values. In this way, a table is created, so that
when the output signal is again measured the processor can
use this table to determine which variable reactance will
lead to impedance matching.
