High Efficiency RF Generator
Model RFG4K-13, 4000 Watts at 13.56MHz
Model RFG4K-27, 4000 Watts at 27.12MHz
The high efficiency range of RF generators are precision units intended for scientific and
industrial applications. Their robust construction using the latest in switch mode and
solid-state design techniques ensure a long and trouble free life even in harsh
environments.
The small size of the unit makes it ideal for use where there is restricted rack space.
It is recommended that the generator be used in conjunction with either a manual or automatic
impedance matching network. Both types are available from Coaxial Power Systems Ltd –
please see the separate brochure for details.
Two models are available:
Model No RFG4K-13, 4000 Watts at 13.56MHz
Model Mo RFG4K-27, 4000 Watts at 27.12MHz
The main features of all models are:
 Efficient Class-E design
 Full-rack, 5U (222mm) high
 Microprocessor display of incident (forward) power, reflected power and unit
status
 Precision power control +/- 1% of set point.
 Fast pulse operation from TTL/CMOS input.
 13.56MHz and 27.12MHz frequencies available as standard.
The output power of each generator is fully adjustable between zero and maximum
power. The feedback control system ensures that the set output power remains constant
and repeatable. Incident (forward) and reflected power measurements are internally
calibrated to give high accuracy throughout the power range.
