XI. Power Amplifier Precautions
Working with RF power amplifiers can be dangerous and even fatal if not handled properly. All
precautions should be taken while operating the iSpin-NMR as an RF power amplifier is used in its
operation. Output voltages can reach values greater than 100 V peak-to-peak and can be fatal.
Follow these steps to avoid damaging the amplifier or inflicting serious injuries.
Connecting & Disconnecting Power Amplifiers
When connecting the power amplifier, follow these steps to avoid damaging the amplifier or
inflicting serious injuries.
1) Apply the load to the amplifier (make sure a load is ALWAYS present when working with
power amplifiers).
2) Apply the DC power to the amplifier.
3) Apply the RF input to the amplifier.
Repeat the steps in reverse order when disconnecting the amplifier.
Power Considerations
Make sure the following considerations have been made before applying power to the amplifier.
1) Be sure your load can appropriately dissipate the maximum power being applied by the
amplifier.
2) When applying an RF signal, work with low duty cycles to limit the power being
dissipated. The duty cycle ratio should be below 1% for safe operation.
