Overview
The Com-Power PAM-840A is a wideband, high gain, bench top microwave preamplifier. The PAM-840A has a frequency range of 18 GHz to 40 GHz. This preamplifier is primarily intended for EMC applications; however, it may be used for other applications that require low noise and high signal amplification.
The simple front panel consists of two 50 Ohm matched air core 2.9 mm connectors for input and output. The preamplifier was designed to have flat gain with minimal variation over the entire frequency range. The flat gain helps in taking fast adhoc readings during troubleshooting, R&D phase. The high gain and low noise figure of PAM-840A increases system sensitivity of effectively all measurement systems. It is very effective in measuring low level signals during Electromagnetic Interference (EMI) testing. It has low VSWR and high reverse isolation.
Each preamplifier is individually calibrated using equipment traceable to National Institute of Standards and Technology. Individual data and certificate of calibration is shipped with each unit. The PAM-840A is battery powered to avoid any noise effects of power cables. It can also be powered by 15 VDC, 500 mA power adapter (provided with the unit)
