Radio transmitter system especially for long, medium and short wave bands

摘要

The system has at least one transmitter (12), at least one feeder line and at least one transmission antenna (14). The antenna is connected via a matching circuit (13), containing capacitances and inductances or line transformers, to the transmitter output for impedance matching. The matching circuit has a first matching stage (15) in the form of a band pass filter in which the input and output interact with each other via coupled inductances. The first matching stage is connected in parallel or in series with at least a second matching stage (16).
