RF Amplifiers For Magnetic Resonance

The Tomco Technologies range of pulsed RF amplifiers for magnetic resonance applications offer superior performance with specifications tailored for the requirements of
NMR , NQR , MRI , EPR/ESR/ENDOR

Key features of Tomco amps that make them ideally suited for magnetic resonance are:-

  • Fast blanking speed (<1 microsecond)
  • Very low interpulse noise (<10dBm above thermal)
  • Clean, high fidelity pulse amplification
  • CW operation at reduced power
  • Optional extra of peak power limiting for probe protection

The Tomco pulsed RF amplifiers for magnetic resonance can be configured as single output systems or as multi-channel systems suitable for shimming.

Commonly used Tomco amps in magnetic resonance systems:-
AlphaS 100kHz to 30MHz
AlphaSA 500kHz-150MHz
Gamma 5-400MHz
Delta 100-600MHz
