Re: LF: RE: Matching Ropex (score: 1): Author: Johan Bodin <[email protected]>; Date: Thu, 17 Feb 2005 11:40:17 -0100; A Pi filter with all X = Zo behaves like a lumped circuit version of a quarter wave transmission line. For 50 ohms and 136.75 kHz that is: C1 = 23.3 nF across, L = 58.2 uH along, C2 = 23.3 nF across; /rsgb_lf_group-archives/html/rsgb_lf_group/2005-02/msg00214.html (9,489 bytes)

RE: LF: RE: Matching Ropex (score: 1): Author: "Dave Pick" <[email protected]>; Date: Thu, 17 Feb 2005 13:05:50 +0100; The puzzle is why the Ropex has problems with a 50 ohm match at 136kHz if the coil is grounded? The match is the same on an SWR bridge whether the pi cct is in circuit or not. The Ropex protection cc; /rsgb_lf_group-archives/html/rsgb_lf_group/2005-02/msg00215.html (10,047 bytes)
