Hey! Welcome to the club - sometimes we use them in repairs - like "WHY DO THEY DO THAT" Wham - Wham Wham ...
No, er - well I guess it doesn't hurt to let others know how you feel about these things... but still - GRRR...
I remember the older times where Motorola used to show why they did certain things.
Was it you that mentioned the IMD THD issues that Single Pill designs they produced took care of?
There was a thread or two about how one pill can produce just as much as a two pill - although much of the ruckus over it - there were provable points amongst the efforts - that showed real world results - however used in Bandwidth limitations, narrow as they may be - the sky was the limit - but in the Broadbanding of the platform - a lot of the effort was then taken to matching networks for the conjugate match. The device loses it's glory when it comes to wide dynamic range range and band width performance - one or the other, but not both.
I am not sure if I caught it right, but in everyone's effort to find the right matching network design - the Motorola "test jigs" showed that a single pill design - if done correctly - did not need a filtering Pi network because their Die design as well as the Test Jig itself - took care of the IMD / THD problems - but it narrowed the bandwidth the device needed to perform in. This process of the test jig performance design - took / demonstrated the devices singular ability to perform cleanly.
Well I just wanted to kinda extend on that; for things that I'm noticing We aren't doing anymore that somehow either went away because they didn't think IMD and THD were such issues, or they just got lost in the Translation somehow.
But with these new Pills arriving on our shores - knockoffs and copy-catters - I think they feel that were are responsible for their garbage they send to us and we have to produce the results - not the other way around.
So since I'm losing access to those BJT's of yesteryear (read TO-220 style stuff not the others) - I've had no choice but to segue over to the MOSFET designs and even then, their graphical design overlays and "slice thru" structure and "open platform architecture" the developers were willing to produce in a plethora-show of die designs and overlays even on their websites - are now wrapped up in secrecy - strange world we live in now...
You're not alone in your endeavors - it's been interesting here too...
