Power Amplifiers

RF Power Amplifiers

The RF power amplifier range from Laplace is specifically designed for EMC Immunity testing according to IEC61000-4-3 and IEC61000-4-6. These are compact units with characteristics matched to the requirements of IEC standards. These RF amplifiers utilize fully isolated linear MOSFET or advanced GaAs FET devices, which provide high gain, wide dynamic range and excellent third order intercepts. High efficiency and reliable operation are achieved by employing unique RF combining circuits, RF microstrip networks, sophisticated thermal design, custom machined housing and heavy duty components. The high power RF amplifiers undergo extensive burn-in prior to final test and inspection.

Test methods covered include:

  • CDN
  • BCI
  • EM Clamp
  • Test cells
  • FAC and SAC chambers

The amplifiers all feature 50 ohm input & output impedance, thermal and mismatch protection, standby switch and internal fan assisted cooling.
