‘ello necks!Hope everyone’s alright and is ready for their annual New Year’s Eve alcohol poisoning!
Just got these in the post today, it’s a driver board ‘design’ rather a mashup because I didn’t design any of it haha I just made a layout.
The vfo is the NRG50mw feeding two paralleled NSVF6003SB6T1G or BFS20 for ~1 watt output or ~500mw respectively - These are estimates but I think it will be somewhere in that ballpark.
The PLL is Albert’s CMOS pll that he’s always raving about haha.74HC4040,4060,4046 and 393.
The reason I chose this pll is because these Ic’s aren’t obsolete and are cheap as chips!I would like to eventually find replacement parts for all the old parts.Also the board is nice’n’compact at 80mm x 75mm.
If all goes to plan this will be a very cost effective driver board that can be left on the roof of a tower block and won’t be a big loss if it gets nicked by some thief twat and 3am!

Looks nice. What I usually do before getting boards made is test the design first on a sheet of copper clad, solder all the component earth points down to the copper and interconnect the rest above the copper where required, making sure to keep all connections as short as possible (very important for RF). This way you can test different component configurations very easily, add and remove inductors of different sizes, add new RF stages and test different interstage FET’s - all with relative ease. Once the design is right I lay it out properly in Altium or other CAD software, I then get 2x prototype boards made at a local manufacturer.

Thanks nrg!haha altium.....I did this all on Easyeda pcb software :lol: . I was considering getting the chems together to do a test etch at home but JLCpcb is so cheap It’s not worth it!

Can you share the easyEDA file as I’ve been thinking of doing this combo and will save time. Or schematic ?

Some of the numbers are not in the right place , you probably fix it by now i’m guessing

This thread is from 2019 which about as long ago as the OP last logged in to this forum.
.....Never say never but good luck getting a reply. :tup

It’s ok, going to look at the sinus 1w b2 pll
