(Bedford, MA) recently introduced a compact, high-voltage pulse modulator
for applications including generating vacuum and atmospheric plasmas, semiconductor production, surface sterilization, R/D, and materials modification.
has introduced PowerMod, a compact, high voltage pulse modulator
that can be configured for a wide range of current and voltage and provides full repeatability with low droop.
If voltage signals are taken into consideration, the result of the pulse modulator
is 110-155 V and the result of the space modulator is 140 [+ or -] 8 V.
The generator is fully integrated into one 24" W rack and includes a pulse modulator
, power supply, and controls.
Each of the two internal signal sources provides output power of +16 dBm, low harmonics of -59 dBc, a 40-dB power sweep range, and a built-in pulse modulator
and signal combiner.
The model SWM-DJV-1DT-2ATT is an ultrahigh speed pulse modulator
with " 2 ns rise and fall times with a [less than or equal to] 20 ns minimum pulse width at 50 percent duty cycle.
In the transmitter, a pulse modulator
(5) modulates the power amplifier (4) to generate the interrupted CW signal.
The [PowerMod.sup.TM] HVPM solid-state, high power pulse modulator
features fast rise and fall times of 5 us for use in ion implantation, high energy physics, semiconductor and flat-panel display manufacturing.
