4. R: [AMPS] broadband L at output (score: 1): Author: philk5pc@tyler.net (Phil Clements); Date: Thu, 20 Jan 2000 20:01:21 -0600; You need exactly the same loading capacitor that you would need for a Pi-L network. The savings is that you need no L coil and no padding capacitors. The trade-off is that your harmonic suppression; /archives//html/Amps/2000-01/msg00444.html (8,847 bytes)
5. R: [AMPS] broadband L at output (score: 1): Author: ko0u@os.com (Steve Harrison); Date: Fri, 21 Jan 2000 02:02:00 +0000; There are plenty of examples of 4:1 toroidal transformers used at the multi-KW range, usually to step back up to 200 ohms (or even higher). Proper core design and choice is necessary, of course, but; /archives//html/Amps/2000-01/msg00446.html (8,871 bytes)

R: [AMPS] broadband L at output (score: 1): Author: Peter_Chadwick@mitel.com (Peter Chadwick); Date: Fri, 21 Jan 2000 10:55:17 -0000; You may well have problems meeting FCC harmonic requirements with just a pi. You certainly will not meet European requirements, or the ITU Recommendation SM.329-7 on spurious emissions with just a pi; /archives//html/Amps/2000-01/msg00450.html (7,318 bytes)
