Wideband High Gain Preamplifier: To 18 GHz

A wideband high gain preamplifier Model PAM-118A is a bench-top microwave preamp operating over 500 MHz to 18 GHz. This preamplifier is primarily intended for EMI / EMC applications; however, it may be used for other application which requires low noise and high signal amplification. The simple front panel consists of two 50 Ohm matched precision N-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 readings during trouble shooting, R&D phase. The high gain and low noise figure of PAM-118A increases system sensitivity of effectively all measurement systems. It has low VSWR and high reverse isolation. The PAM- 118A 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).
