AO Q-switch Driver (RF Driver)
1. QSD Series Q-switch Driver
A high power RF driver module is available in output powers of 50W, 75W or 100W. Powered from
220VAC or 110VAC, the modulation inputs allow either full digital control or activation of an internal
pulse generator. First pulse suppression is automatically implemented.
Main Specifications:
RF power output: 50W, 75W or 100W
Frequency: 27.125MHz
VSWR: ≤1.2:1
Modulation repetition rate: 800Hz-50KHz
First pulse suppression
Modulation control inputs: digital TTL, till 100kHz
Driver over-heat, Q-Switch over-heat
Internal over-temperature protection and over-current protection
Digital display of frequency
Supply voltage input: 220VAC/110VAC, <150W
Model Numbers:
QSD-2750 (50W), QSD-2775 (75W) or QSD-27100 (100W)
Dimension:
19” 2U frame, 483×88×200mm
2. R390 Series Q-switch Drivers (RF Driver)
R390xx-yyDMzzz-A (50W, 100W)
A compact high power RF driver module is available in
output powers of 50 or 100W. Powered from 28VDC, the
modulation inputs allow either full digital control or activation
of an internal pulse generator. First pulse suppression is
implemented through either analogue modulation, RF off
analogue control, triggered first pulse suppression, or
triggered pre-pulse kill, as described in our FPS guidance
notes. On board LED’s and TTL logic outputs monitor driver
status and cooling is through forced air over the heat sink.
