Hi all,
Sometime I found a term 'RF transistor' to a simple TO-92 transistor which has transient frequency little higher than 300MHz. In this case do we need say RF transistor to a UHF transistor?
Also there are some transistor can go to some MHz like BD136 (maybe) and I found somewhere used as 7MHz ham radio RF driver stage. But we do not say it RF transistor. MRF476 (3 watt) also called RF transistor with 3W power and has 50MHz fT, but 2N3904 has 250MHz fT and it's called General Purpose transistor.
Trying to understand specialty of 'RF' (Radio Frequency) term and chemistry on transistor in such case.
