/members-area/b/blog/posts/simple-analog-jfet-switch---part-2-linear-range-and-limitationsI reviewed an analog small signal switch in post 1: Simple analog JFET switch - part 1: schema, simulate and test .Here I&#39;m checking what the limits are - the small linear part of the operational region where the P-channel JFET acts as a resistor.

Thank you for posting this! I found it while searching for a replacement JFET for my Grundig TS1000 reel to reel recorder. This recorder uses a JFET type GF405 to switch audio signals. There is no replacement nor information for the GF405 on the net. T12 on the schematic.&nbsp;</p> <p>Could you please give me a tip witch JFET type I could use as a replacement? Are there some types that &quot;sounds better&quot; for audio applications?</p> <p>Thank you [emoticon:33306c418930400bac28808410f8ac8b]&nbsp;<img src="/resized-image/__size/1280x720/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-5c3f4115-cec2-4f79-a5f6-25ff5564e147/IMG_5F00_20230721_5F00_153703.jpg" alt=" " /><img src="/resized-image/__size/1280x720/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-5c3f4115-cec2-4f79-a5f6-25ff5564e147/Screenshot_5F00_2023_2D00_07_2D00_21_2D00_15_2D00_07_2D00_59_2D00_09_5F00_e2d5b3f32b79de1d45acd1fad96fbb0f.jpg" alt=" " /></p><img src="https://community.element14.com/aggbug?PostID=9519&AppID=75&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/members-area/b/blog/posts/simple-analog-jfet-switch---part-2-linear-range-and-limitationsTue, 23 Jun 2020 18:00:51 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:5c3f4115-cec2-4f79-a5f6-25ff5564e147DAB0<p>Great post Jan.</p><p>&nbsp;</p><p>It has been a while since I last played with some FETs so I found your post very interesting.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=9519&AppID=75&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/members-area/b/blog/posts/simple-analog-jfet-switch---part-2-linear-range-and-limitationsMon, 22 Jun 2020 20:07:32 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:5c3f4115-cec2-4f79-a5f6-25ff5564e147jw07520<p>Interesting and very nice follow up on part 1.</p><p>&nbsp;</p><p>John</p><img src="https://community.element14.com/aggbug?PostID=9519&AppID=75&AppType=Weblog&ContentType=0" width="1" height="1">
