UEK-3000 Down convertor for AMSAT AO-40

AO-40 downconverter 13cm to 2m or 70cm.
As a successor to the worldwide utilized UEK-2000SAT the new UEK-3000 is further improved and offers to IF frequencies for even better versatility.
The printed circuit board material is made out of ceramic/glass fibre substrate. Through the use of a selected HEMT a very low noise figure of 0.7dB for the whole converter system is achieved. The preamp alone has a noise figure of 0.5dB. The amplification factor of 32dB was choosen for best satellite operations practices. With the tuneable helix filters a high selectivity and excellent IMD suppresion is achieved.
