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

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?
Best regards,
Martin Elfvelin
