You know you want the current to be 70 mA. I guess the 2N would be a smidgen better. Sign in Sign in Remember me Forgot username or password? There are plenty of FETs available for which that would be true. Originally the was in cascode with a 2N – it almost worked.

Or briefly touch the drain to the gate to turn the LED partly on, then float the gate again.
And then let it float in either state for hours. Previous 1 2 3 Next. It was with the BSS but it’s quite similar. On Sun, 11 Jul Some of us are easily amused.
Of course, re-radiation can dafasheet some feathers with the authorities.
The ideal resistance value in that case would be 1. The LED brightness will very slowly creep up or down. Use another domain or send PM. Please find the supply details in the image.

Andy aka k 10 Your calculated answer is correct, but you meant to show division by 0. My intention was to re-radiate DAB VHF high band from a communal aerial socket in one corner to the radio in the diagonally opposite corner. Find one that has a low Rds. Your biggest problem may be that RDS on will vary device to device and is a significant percentage of R Tony EE rocketscientist 62k 2 21 This is what you need to learn; Never select parts or a design until you understand exactly how it works.
Home Questions Tags Users Unanswered. Is datwsheet Lay’ a play on words? Dividing two dimensionless values can’t result in units of Ohms. The block of flats has a master aerial with a bunch of co-ax cables running along the wall to each flat.
Email Required, but never shown. Also, the units are missing on the left side of your equation. You still haven’t fixed the units error.

Datasheer best way to deal with the drop across Q3 is to make sure it is small enough so that you can ignore it. Anyway, you need at least 2. But choose a different mosfet. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
Find R1 by using Ohm’s Law. Or less than a quid in rightpondian. What is the formula for that? Some of the bigger MMIC, the ones with a grounded tab that can be soldered onto copperclad for heatsink, should also work. Sign up using Email and Password.
That says that the resistance of a resistor is the voltage across it divided by the current thru it. The 2N version will have a little more lead inductance, but that can be tuned out. You should think about formally accepting an answer from one of those below.
Olin Lathrop k 30 Again, manipulating a bunch of dimensionless numbers can’t ever result in a answer in units of Ohms.
