The PA 2522 from Langer EMV-Technik is a Pre-Amplifier that operates from 10 MHz to 22 GHz. This preamplifier provides a gain of 25 dB with a noise figure of 3 dB. It is designed to amplify weak signals from near-field probes during measurement and is characterized by low noise behavior and a constantly high dynamic range over a very wide frequency band. The preamplifier connects a near-field probe of a suitable frequency range and corresponding cable to achieve the desired amplification, thereby ensuring optimum performance. It is ideal for EMC Applications. The amplifier requires a DC supply from 7 to 12 V and consumes 190 mA of current. It is available in a surface-mount package that measures 50 x 38 x 14 mm.
