Jul 21, 2015 · I've been trying to figure out how to select transistors for radio frequency circuits but not being able to find much information on the web. There are many radio circuits and plenty of guides of how to bias transistors and different amplifier configurations but not so much on selecting the right components for high frequency applications.

Nov 18, 2018 · Description : This transistor designed for use in general-purpose amplifier and switching application. Features. 1. Complementary to 2SB688 2. Recommended for 45 ~ 50W audio frequency amplifier output stage. For a transistor compliment, I'm thinking 2N3904/06 and BD139/140. I can't get 1980s transistors and I'm not willing to try. My experience is that a good amplifier will perform well with any compliment of transistors, as long as their ratings are enough to handle the power in the amplifier. I'm looking for feedback on my decision. Apr 04, 2012 · To avoid paying £3 postage on a 50p transistor, I'd like to get this at Maplins. Unfortunately, the very nice and helpful guy at the shop says he knows all about resistors, capacitors, and diodes, but not about transistors. So he couldn't help. Can anyone tell me which transistor in the Maplins catalogue is equivalent to this BD139? Select a replacement transistor with equivalent Ft: It is necessary to ensure that the replacement transistor will be able to operate at the relevant frequencies, so a similar or slightly higher Ft is advisable. Don't go for a transistor with a much higher Ft as this may increase the risk of oscillation.
