1. LF: Re: RF ammeter question (score: 1): Author: "James Moritz" <[email protected]>; Date: Tue, 11 Jan 2011 14:48:09 +0100; Dear John, LF Group, The 1N4007 and similar HV rectifiers have a notoriously slow recovery - it is sometimes seen in amateur literature used as a PIN diode for this reason. So one could expect proble; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-01/msg00090.html (11,878 bytes)
2. LF: Re: RF ammeter question (score: 1): Author: John Rabson <[email protected]>; Date: Wed, 12 Jan 2011 08:55:50 +0100; Thanks Jim. With 1N5822 diodes response is within +/- 1 dB from 10 to 300 kHz. When I have the 1N4148s I will try them. 73 John F5VLF; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-01/msg00263.html (10,129 bytes)
3. LF: RE: RF ammeter question (score: 1): Author: Rik Strobbe <[email protected]>; Date: Tue, 11 Jan 2011 12:37:40 +0100; John, 1N4148 is a relatively fast small signal diode (4ns switching time) It can handle 100V (reverse) and 200mA 1N4007 is a rectifier diode (1000V / 1A). My datasheet doe not mention the switching t; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-01/msg00364.html (10,741 bytes)
4. LF: Re: RF ammeter question (score: 1): Author: "Alan Melia" <[email protected]>; Date: Tue, 11 Jan 2011 12:39:43 +0100; Hi John most probably......... the 1N4148 is a fast switching diode whereas the 4007 is intended to rectify at about 1amp, so has a bigger area junction and a lot more capacitance, and probably a lon; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-01/msg00686.html (11,034 bytes)
