Dear all, After evaluating options for VHF and UHF power amplifiers for the transmitting chains of our ground station I have reached a preliminary conclusion on what to procure. Power Amplifiers VHF PA MKU PA 2M <https://shop.kuhne-electronic.com/kuhne/en/shop/power-amplifiers/MKU+PA+2M60W+HY++VHFMOSFET+Power+Amplifier/?card=633#_tab_content1> €379.00 PA power supply RSP 150 W 12 <https://shop.kuhne-electronic.com/kuhne/en/shop/power-amplifiers/Schaltnetzteil++RSP+150+W+12/?card=1676> €49.00 PA heat sink SK 150-62 <https://shop.kuhne-electronic.com/kuhne/en/shop/power-amplifiers/SK+150++62+heat+sink/?card=734> €36.00 Heat sink fan 12V HP fan <https://shop.kuhne-electronic.com/kuhne/en/shop/power-amplifiers/Fan+60+x+60++12+V+HP++high+power+fan/?card=311> €18.20 UHF PA MKU PA 70cm <https://shop.kuhne-electronic.com/kuhne/en/shop/power-amplifiers/MKU+PA+70CM60W+HY++UHF+MOSFETPower+Amplifier/?card=650#_tab_content1> €399.00 PA power supply RSP 150 W 12 <https://shop.kuhne-electronic.com/kuhne/en/shop/power-amplifiers/Schaltnetzteil++RSP+150+W+12/?card=1676> €49.00 PA heat sink SK 150-62 <https://shop.kuhne-electronic.com/kuhne/en/shop/power-amplifiers/SK+150++62+heat+sink/?card=734> €36.00 Heat sink fan 12V fan <https://shop.kuhne-electronic.com/kuhne/en/shop/power-amplifiers/Fan+60+x+60++12+V/?card=1472> €10.50 For a total cost of 966,20 euro. Here are some key features of both amplifiers: - 60W output power - 34 dB small signal gain UHF, 36 dB VHF - 12V enable pin for on/off control - Integrated harmonic filtering - SMA input, N-type output Using these we should get a link margin of ~19 dB for APTAS which in turn should give us less than 10^-10 bit errors per second on telecommands. Please feel free to raise objections or give feedback. From Rickard Nilsson I would like to hear if you are interested in joining the order with us so we get 2 of everything?
