Preamplifier with High-Gain


18 GHz to 40 GHz

Preamplifier with High-Gain

  • The PAM-840H is a wideband, high [50 dB] gain, bench top microwave preamplifier. It has a frequency range of 18 GHz to 40 GHz.
  • The PAM-840H preamplifier increases system sensitivity, thereby enhancing the capability of measurement system to measure low level signals. It also provides input isolation to your spectrum analyzer or receiver.
  • The PAM-840H may be powered by its internal battery pack or the supplied external AC/DC power adapter/battery charger.
  • Each preamplifier is individually calibrated using equipment traceable to the SI through the National Institute of Standards and Technology (NIST) or a recognized National Metrology Institute. Individual calibration data and certificate of calibration is shipped with each unit. ISO 17025 accredited calibration is also available upon request.
