The PAM-840H from Com-Power Corporation is a Pre-Amplifier that operates from 18 GHz to 40 GHz. It has a low noise figure of up to 3 dB and a high gain of 50 dB with a gain flatness of +2.5 dB. This amplifier is primarily intended for EMC applications and other applications that require low noise and high signal amplification. It consists of two 50-ohm matched air dielectric 2.9 mm connectors for RF input and RF output in front panel. This amplifier has flat gain for taking fast ad hoc readings during troubleshooting and R&D phase. It increases system sensitivity, thereby enhancing the capability of measurement systems to measure low level signals. This NIST and ISO 17025 accredited amplifier has a 1dB compression output power of +8 dBm and a reverse isolation of less than 50 dB. It is available in a enclosure that measures 203 x 152 x 60 mm, weighs 1.13 kg, and requires an AC supply.
