Great, audioguru!!!!! ;) You are a very good teacher! Thank you a lot! PS: what's your job?! See you! Errand

Thanks audioguru! I'm jet a bit confused... Take a look at "standard" Colpitts Oscillator (attached in the post). There are some substantial differences: 1. there isn't the emitter resistance 2. there isn't the second resistance needed to polarize the transistor (from base to Val) 3. C2 is connected to Val, instead it should be connected to ground (provided the presence of Re!) Could I ignore "Re" and "Rbias"? Could I connect C2 to Val instead of ground? (obviously in signal analysis it doesn't matter: in small signal analysis power source are replaced with "short circuits")

Hi all! I'm starting with RF design (I'm experienced in digital and analogue electronics)... I found this design on the web. Could you help me to understand the simple design? ??? I've already saw oscillating circuits, but this one is different from all the circuit teached at school... Thanks!
