2017年4月18日 · Details about the NE602 and NE612 mention ability to generate AM, but I was assuming these ICs are meant to produce double sideband (DSB-SC, no carrier) by default. …

2023年2月10日 · I tried all the usual suspects: NE602, SA602, NE602 & SA612. Nada! I was so desperate to search "rf mixer ic" in case of psudonames. Still nada! Some say differently as to …

2018年7月18日 · Hi! I am trying to find spice model for the NE602 mixer or the SA602 or the SA612 I have done a search on the web with no success finding any models.

2015年12月22日 · Thanks for these videos, Alan - as always, a nice clear and concise explantion of the subject. I often find myself referring to them as a refresher or referring others to them to …

2018年5月2日 · I guess there are higher frequency Gilbert cell type parts NE602, NE612, HFA3101, but a bit more expensive. Your single transistor mixer is basically just a single diode …

2021年9月12日 · The NE602 (which is now really SA602/612 - original NE602 masks lost in a plant fire) are Gilbert cell mixers, which means that on the LO port they like switching levels, …

2018年8月1日 · Transmitting voice over shortwave is quite fascinating to me. But whenever I google for shortwave AM phone, the results turn out as cw transmitters.Well, I've already …

2016年2月12日 · Hi, If I already have a LO signal, how should I connect to a NE602/SA612? For instance, looking at the block diagram in the datasheet (see attachment), it looks like I could …

2020年5月3日 · If you want to do dead-bug style with a DIP-8 package, I will mention that I have successfully purchased NE612 and NE602 DIP-8 chips on ebay that work as advertised. I tend …

2017年8月24日 · Last week I traced back the cause at the very beginning of the tx chain, in the 4MHz LO (which is also a NE602 - SA612AN, actually). Measuring with a scope the LO I …
