Crystal receiver antenna

时间:04-07 整理:3721RD 点击:
Hi all,
I want to use a ceramic resonator for am demodulator input. Will this circuit work? (On attachment)

You can try it but I doubt it will work well. It certainly can't be tuned and its bandwidth may not be usable. The characteristics of resonators vary, if it doesn't work in parallel mode, you could try it in series mode instead by wiring it in series with the antenna, with a capacitor of 47p or thereabouts on each side to ground.

Brian.

Thank you Brian.
