| Zusammenfassung: | The HF circuit has an oscillator (VLO) providing a HF carrier signal, a power amplifier (Amp) for amplification of the HF carrier signal, a phase regulation circuit for suppression of phase errors in the output signal of the power amplifier, an amplitude regulation circuit for suppression of phase errors in the output signal from the power amplifier and a signal coupler (RK) supplying the power amplifier output signal to the phase regulation circuit and the amplitude regulation circuit. The bandwidth of one of the regulation circuits is determined via a bandwidth setting device (BBE), holding a characteristic for the relationship between the bandwidth of the regulation circuit and measured values for a parameter dependent on the regulation circuit bandwidth. |
