Just trying..
OK, Here's a picture of the world's smallest 80 watter
SV.. This thing looks like a dissaster zone from Gaza. To expect any reasonable results you do need to "clean up" your technique.. I won't go to lenghts - but just look in the very centre of your picture.. see the 520Ω? resistor there accross the RF transistor? If this is not a dry joint .. I'll shut up. You do have "blobbes" of solder and a lot of flux all over the place.. (btw- that resistor looks like it has been attacked with a chisel).
If there are to be any comparable results you'e looking for dear
SV, every "project" must be "neat" to be consitant with your tests. This is even more so when in RF designs.
It is only suggestion of mine that you throw this "thing" into a bucket, poure a litre of methylated spiryt (and set it alight..
) .. No!!!
No - joking
.. pour the metho in and let it seat the for 3 days. Then, as you're taking it away, brush off all the flux away (it should have resolved all but some by then).
Then with a good magnifying glass, take some crticism of yourself and "re-do" the joints that (surely), even to you do not look right..
[I do pride myself on the best soldering joints there are and I did fail my own tests under the microscope more times than I can even remember]
Microscope is not reqired but a good x 15to20 watchmakers glass will tell you more than I can say..
Only after rectifying these joints you do not like yourself, you will have the RF AMP "worthy" sharing your comperative experiences with.
Also, if you do want to improve your design.. buffer, isolate supplies.. as suggested in many posts earlier.
[Think of it also along these lines; if the AMP overloads the Driver, then the driver probably overloads the Mixer..]
Most of all - if your assembly technique is not up to standard - do not expect results even if you had used 100s of PICs..
