Home Forums Job & Work Life 전자부품에 대한 질문- 옵토 커플러와 릴레이 전자부품에 대한 질문- 옵토 커플러와 릴레이 Name * Password * Email I have several SSRs on hand and one day I was going to use it for the in-rush current limiting circuit of a high power RF linear amplifier. Unfortunately, these were not zero cross-over types. I didn't know whether it would have any meaningful effect on the Class AB RF output or not (some ppl claims it does), but it would have certainly created hashing to nearby receivers, if no additional filtering was employed. I opted to use a mechanical relay. We typically use reed relays for low power (up to about 100W) signal switching, low latency switching and vacuum relays for high voltage/power switching (order of few KW) . PIN diodes are also often used for RF signal routing. For generic switching circuits (e.g. bias), power mosfets do a good job. I do see a lot of SSR uses in control applications. I agree to the terms of service Comment
