1. [AMPS] Recycling filament (score: 1): Author: w8jitom@postoffice.worldnet.att.net (w8jitom@postoffice.worldnet.att.net); Date: Thu, 26 Jun 1997 11:38:28 +0000; I have to agree with Peter, I can't imagine a 723 being a "good choice" for an IC near strong RF fields. I seriously question the carte blanche statements about bypassing ("do this, it always works"); /archives//html/Amps/1997-06/msg00356.html (8,170 bytes)
2. [AMPS] Recycling filament (score: 1): Author: measures@vc.net (Rich Measures); Date: Thu, 26 Jun 97 13:53:58 -0700; Instead of trying to imagine, why not try trying to see if it works, Mr. Rauch? - If the designer does not bypass for the range of frequencies involved, what then? The Vcc multi-C bypass technique I; /archives//html/Amps/1997-06/msg00358.html (8,795 bytes)

Warm-up or down time is like an RC time constant curve. When charging a capacitor, the last few percent takes; /archives//html/Amps/1997-06/msg00359.html (8,235 bytes)

The shielding and layout is probably more important than the specific value of bypass comp; /archives//html/Amps/1997-06/msg00362.html (10,097 bytes)

[AMPS] Recycling filament (score: 1): Author: w8jitom@postoffice.worldnet.att.net (w8jitom@postoffice.worldnet.att.net); Date: Fri, 27 Jun 1997 09:59:01 +0000; Hi Bill, While this is something I rarely consider, I'm not aware of the temperature having a different slopes for increase and decrease anywhere on the curve, unless the filament were removed and r; /archives//html/Amps/1997-06/msg00365.html (8,946 bytes)
7. [AMPS] Recycling filament (score: 1): Author: crb@nanoteq.com (Chris R. Burger); Date: Fri, 27 Jun 1997 16:25:24 +200; Yeah, but the temperature variation is relatively small. You start at something like 300 K, and end up something like 100 or 200 K higher. So, we're looking at a range of something like 20 to 40%.

8. [AMPS] Recycling filament (score: 1): Author: measures@vc.net (Rich Measures); Date: Fri, 27 Jun 97 07:39:42 -0700; I believe that the circuit designer designs his own luck. That's why solid state RF amplifiers typically use multi-values multi-C DC supply RF byassing. That's why I used it in my 723-based screen s; /archives//html/Amps/1997-06/msg00367.html (9,463 bytes)
