Power amplifier
At its core is an innovative voltage amplification stage that consists of linearized
amplifiers operating up to a cut-off frequency of 80MHz. Current amplification is
done in three stages, each with a narrow, almost linear operating range.
Power supply
Four switched mode power modules with multi stage filter networks provide the re-
quired power for the amplifier. Induction of noise is omitted by physical separation
from the amplifier boards and effective shielding. Switched mode power supplies
provide supply voltages that are more stable and lower in noise than other power
supply technologies.
