Circuit arrangement for obtaining a constant field strength of an HF signal radiated by a transmitting device with exchangeable antenna |
摘要 |
A circuit arrangement is described with the aid of which a constant field strength of an HF signal radiated by a transmitting device (10) having an exchangeable antenna (12) can be achieved. Associated with the exchangeable antenna (12) is an antenna-specific component R1 from which in the operating state a control signal can be tapped after connection of the antenna (12) to the transmitting device (10). Said control signal is applied in the transmitting device (10) to an assembly (28) for influencing the transmitting power.
