With the KU SG 2.45–250 A Kuhne electronic presents a high power microwave generator for the ISM band around 2.45 GHz. This device is especially designed for “Microwave Heating”. But it can also be used for propagation tests of electromagnetic waves, EMC tests, plasma generation and various other applications.

The KU SG 2.45–250 A can be controlled via a serial interface (3.3 V level). Warnings and alarms are signaled through a LED on the signal generator.
The RF output signal can be adjusted between 2400 … 2500 MHz in steps of 1 MHz; the output power is adjustable between 0 … 250 W in steps of 1 W.
  • Adjustment of frequency in steps of 1 MHz
  • Adjustment of output power in steps of 1 W
  • Frequency-Sweep function
  • Pulse-function (pulse width and duty cycle adjustable)
  • Algorithm to find the frequency with minimum reflection
  • Isolator for protection against high VSWR
  • Monitor function of VSWR and (steps adjustable)
  • Monitoring of transistor temperature
  • Switch-off if transistor temperature is too high.
  • Monitoring of forward power
  • Monitoring of reflected power
  • Under voltage warning
  • ON/OFF – Control over interface or pin (ext. voltage)
  • Warming or heating through microwaves
  • Plasma generation
  • Investigation of propagation of electromagnetic waves
  • EMC-tests (electromagnetic compatibility)
Please notice the following:
  • The recommended combination of heat sink and fan(s) is only specified for an ambient temperature of 25 °C.
