I have filter in which I must use switch diode for desired band pass. So, in original schematic is used BA423 (AM band switch diode), in the other hand I can buy BA243 (Diode switch). Working frequency of switch circuit is 10,7MHz. I was noticed that BA243 have 50....1000MHz frequency range. (hm)
Question is; Can I use BA423 instead of BA243 ?, and "AM band diode", does that mean that this diode is for amplitude signals, or for low frequencies of AM band..
Thanks,
