Amplifiers

Amplifier for Particle Accelerators

HBH develops and fabricates custom designed power amplifiers for particle accelerators.
A modular concept facilitates fast installation and easy maintenance. A smart monitoring and control system ensures reliable operation.
The amplifiers can be provided in a frequency range from 80MHz to 3GHz and in a power range from 80kW CW to 500kW pulse operation.


Main Design Features

  • High Efficiency:
    • Drain Voltage can be set via Ethernet
      Interface during operation
    • Modulated Power Supply
  • Open- and short-circuit protected
  • 1GBit/s Ethernet Interface for
    remote control and monitoring
  • Water cooled system
8kW amplifier system, cw

Smart monitoring of amplifier parameters

The following parameters are continuously monitored- limits/threshold can be set as necessary

  • Output power
  • Output VSWR
  • Temperature of each transistor
  • Temperature of each load resistordedicated to circulator
  • Power at each load resistor
  • Output power of each amplifier pallet
  • VSWR between each amplifier pallet and circulator
  • Drain current and drain voltage of each transistor
  • Water flow rate

20kW Amplifier for FPC Conditioning, 322MHz

Measured output power of the 20kW amplifier

Highly sophisticated circulator tracking at 80.5 MHz

  • The input return loss of the amplifier must be >15dB to ensure a safe operation of the amplifier pallet.
  • This necessary input return loss is achieved by an additonal coil within the circulator and controling the current of the coil.
  • The input return loss is a function of the power level, reflection factor in magnitude and phase as well as a function of the temperature.
Goal of the tracking algorithm is to stay in the valley Goal is also to avoid false minimums
