   Hartwig-RF offers a new design of Broadband Preamplifier This Preamplifier may be used by Ham Radio Operators, Radio Astronomy or SDR to boost sensitivity of your scanner. This Preamp will lower the noise figure of any Spectrum analyzer available between 30 and 4000 MHz! Our Preamplifier is built on a PCB with gold plating for low noise and uses a carefully design to prevent self oscillation! We only use high grade parts, like ATC – chips and SMA – Connectors made in Germany. The device is the well known US made PSA4-5043+ which is widely used all over the world. The noise figure and gain were measured at an ambient temperature of 24°C, just if you like to compare – other designers measure at 18°C!! This gives lower noise figure of course! The mechanical size is only 55 x 37 x 25 mm (LxBxH) exclusive connectors. Low frequency sweep shows 1 - stage preamp! Measurement setup: The finest Agilent and Rohde & Schwarz, like HP346B, ZVB 20 and FSV 7 with option K30!   Frequency MHz Gain/dB Noise/dB 138 see plot 0,22 402     " 0,3 1280     " 0,6     "     "     " 4000     " 3,1 These data are typical! For professional purposes we offer a high quality milled housing - your inquiry will be apprechiated! Residents of the European Union must add 19 % VAT/Mwst.
