Amplifier Modules
Our amplifier modules are popular choices for OEMs and do-it-yourself spectrometer builders. They are "brick" modules meaning power amplifier stage only with no power supply or mismatch protection. They do include over temperature protection and can be supplied with suitable heatsink and fan assembly.
They offer a versatile, cost-effective solution for the RF amplifier stage of benchtop magnetic resonance systems.
