Abstract

See full text

A high-frequency (HF) driver circuit for an acousto-optical component includes an HF power amplifier connected to a voltage regulator for supply with a supply voltage and a bias voltage generator connected to an input of the HF power amplifier via a switch. The HF driver circuit can include a measurement device configured to measure a temperature of the HF power amplifier and a compensation device configured to control the bias voltage generator according to the temperature. The bias voltage generator is configured to provide a bias voltage to the HF power amplifier. By switching in the bias voltage, the HF power amplifier can be adjusted to a low quiescent current. By switching off the bias voltage, the HF power amplifier can be very rapidly and effectively blocked. As a result, very rapid switching-on and switching-off times, e.g., in a range of 10 to 50 ns, can be achieved.
