1. [AMPS] PIN stuff (score: 1): Author: watson@epiloglaser.com (George K. Watson); Date: Thu, 3 Jun 1999 12:48:23 -0600; Does anybody know what the downsides would be of placing a pair of PIN diodes in parallel to increase the power handling capability of the circuit. My switch handles 800watts, but gets hot (120C on t; /archives//html/Amps/1999-06/msg00099.html (7,861 bytes)
2. [AMPS] PIN stuff (score: 1): Author: jono@enteract.com (Jon Ogden); Date: Thu, 3 Jun 99 16:34:12 -0500; Hi George, Paralleling PIN diodes is a fine way to increase the power handling of a circuit. I don't see any problems other than the fact that as you point out, junction C is increased. However, tha; /archives//html/Amps/1999-06/msg00100.html (8,338 bytes)
3. [AMPS] PIN stuff (score: 1): Author: Peter_Chadwick@mitel.com (Peter Chadwick); Date: Fri, 4 Jun 1999 09:55:43 +0100; Unless you increase the current, it won't help the power handling. I don't have the 2001 data to hand, but my feeling is that you don't have enough bias current. Incidentally, with PINs, it's the low; /archives//html/Amps/1999-06/msg00104.html (8,687 bytes)
4. [AMPS] PIN stuff (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Fri, 4 Jun 1999 09:29:24 -0400; If you place the PIN diodes in parallel, place them in OPPOSITE polarity for RF but in series for RF. That way the same bias current will pass through the pair (or quad) of diodes. Plus while one dio; /archives//html/Amps/1999-06/msg00114.html (10,871 bytes)
5. [AMPS] PIN stuff (score: 1): Author: Peter_Chadwick@mitel.com (Peter Chadwick); Date: Fri, 4 Jun 1999 15:14:41 +0100; I think Tom actually mean in series for DC. Bearing in mind that the forward RF resistance in the diode is of the order 0.1 or 0.2 ohms, then the series resistance of external parts will tend to domi; /archives//html/Amps/1999-06/msg00121.html (7,810 bytes)
6. [AMPS] PIN stuff (score: 1): Author: watson@epiloglaser.com (George K. Watson); Date: Fri, 4 Jun 1999 11:08:57 -0600; I want to thank everyone for their input. I have a sketch of a circuit with the diodes series connected for DC purposes and paralled for the RF. A word on the bias: The 2110 diode is specifically des; /archives//html/Amps/1999-06/msg00129.html (8,200 bytes)
7. [AMPS] PIN stuff (score: 1): Author: watson@epiloglaser.com (George K. Watson); Date: Fri, 4 Jun 1999 12:58:55 -0600; I have a sketch of what I have coughed up base on the replies and would be happy to provide it to anyone interested. It is a Windows Bitmap, about 35k is all, so not too onerous a download. I think t; /archives//html/Amps/1999-06/msg00132.html (7,306 bytes)
8. [AMPS] PIN stuff (score: 1): Author: W8JI@contesting.com (Tom Rauch); Date: Sat, 5 Jun 1999 11:58:39 -0400; Woops, that's right Peter. It should read in parallel for RF but in series for DC. Chip caps are well down in the milliohm range, but if you use them you need to add external resistance to equalize c; /archives//html/Amps/1999-06/msg00143.html (8,593 bytes)
