   Hartwig Nachrichtentechnik offers a new design of Broadband Preamplifier This Preamplifier may be used by Ham Radio Operators, Astronomy or to boost sensitivity of SDR. With this preamplifier you are able to extend dynamic range of any Spectrum Analyzer by 10 dB or more! Spectrum Analyzers always have a very high noise figure and this limits sensitivity, with this preamp you will see signals that are hidden now in the Analyzers Noise!! 2 - Stages for high gain, precisely milled housing for reliability 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 devices are 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 56 x 40 x 16 mm (LxBxH) exclusive connectors. Measurement setup: HP 8970A, Ailtech 7618, Rohde & Schwarz ZVB 20   100 see above 0,71 200      " 0,63 400      " 0,70 800      " 0,91 1000      " 0,67 1300      " 0,87 1500      " 0,96 These data are typical, each preamp will be supplied with individual sheet up to 1500 Mhz, measured in steps of 100 MHz! Improved design with much higher gain, see diagram above!! 3 years Warranty offered on this professionell preamplifier! Residents of the European Union must add 19 % VAT!
