Key Features
Bandwidth: The first and most obvious benefit from a higher switching frequency is wider bandwidth. The 8500 is the only high-power switch-mode amplifier with a bandwidth that extends to 50 kHz.
Smaller output filter: Switch-mode amplifiers, as a part of their basic design, have high-frequency, high-voltage switching at the heart of their operation. The last stage in any switch-mode amplifier is the low-pass filter that removes the high-frequency switching-noise artifacts from the output signal. Increasing the effective switching frequency by a factor of 10 allows us to reduce the size of these large L-C components used to create this low-pass filter by a similar amount, reducing amplifier size and cost.
Lower magnitude, higher frequency ripple noises: The reduction in output filter component size also makes it easier to implement more complex, higher-order low-pass filters, to greatly reduce output ripple noise. The 8500 series uses this advantage to create output voltages of up to 400 Vp with 1 MHz ripple noises that are less than 2 Vp, with in-band noise specifications similar to low-noise linear amplifiers. If even lower noise floors are needed, simple, small, external filtering can reduce this noise even further.
Optimized for transient waveforms and reactive loads: The 8500 Series of amplifiers are compact and capable. They are able to drive purely resistive loads, at rated power, continuously, but really excel when it comes to reproducing short-duration waveforms and/or driving reactive loads.
