Dear Jeff, havn't actually tried it myself on 137 kHz. But from past experience I'd say that while IGBTs may have less DC loss, they are much slower (especially during turnoff). They can be used as e
Jeff - The "turns" of the mains WD2XDW loop were just distanced parallel loops running in roughly the same plane to reduce the RF copper losses and open up the bandwidth a bit - . I did try a couple
Subject: Re: LF: Re: IGBT in 136 KHz TX? Hello Laurence and all! I use a two turns rx antenna, it works quite good (more directivity). And it are this type of aerial which has just given me the idea
Jeff, Marcus, STGW30NC60WD has a turnoff delay of 120ns. Turn on delay and rise / fall times are better than 30ns. That should be good enough for 137kHz, maybe even for 500kHz. It further has a max.
