SOLD OUT !!
THE UP-100 IS NOT AVAILABLE ANY MORE, BUT :

WE DO HAVE THE BLANK PCB READY 
FOR ALL WHO WANT TO MAKE THE UPCONVERTER. THE BUYER WILL RECEIVE ALSO THE ORIGINAL DIAGRAM AND  THE PARTS PLACEMENT DIAGRAM.

The upconverter design is quite flexible, so design is easily converted to your needs. The placement diagram is collor coded for easy identification of the upconverter parts.

Yellow - power supply 5V regulator with the parts
Blue - canned oscillator wit the filter and attenuator parts
White - mixer
Green - input low pass filter
Pink - output high  pass filter
Red - pre mixing amplifier

The amplifier on board does not have to be used, just make a bridge and you will have a standard upconverter that you can find on the market.

The filters may be made a shorter then originally designed. Air wound coils can be used instead of SMD coils.

Any canned oscillator can be used for the project. 
The upconverter can be powered from the USB port making just a small modification. The Q2 78L05 voltage regulator should not be inserted nor the capacitor C18. Insert the bridge, shorting the input and output 78L05 predicted pads. Use the same pads for powering UP-100 just with the 5V instead of 6-12V.

 
I would like to thanks to all buyers who support this project and all others coming out from my small workbench. I hope that you enjoy the UP-100 and that you find it useful. I receive a nice feedback from you guys all around the world and I am happy that you got the good value for the money invested.

The LNA4ALL project continue and we are preparing a new batch of the LNA.
