Transistor Oscillator Frequency. The output frequency of the circuit is between 18mhz to 60 mhz. In colpitts oscillator the capacitive voltage divider setup in the tank circuit works as the feed back source.
A standard 465 khz if transformer t1 intended for transistor circuits is the lc resonant tank circuit in this oscillator. The frequency f is in hertz whereas l and c are inductance mh and capacitance µf respectively. You really could use any npn transistor.
Collpitts oscillator is generally used in r f applications and the typical operating range is 2 0 k h z to 3 0 0 m h z.
In a transistor colpitts oscillator c1 0 001 µf c2 0 01 µf and l 5 µh. The frequency of oscillation in mhz will be a 2 37 mhz b 10 00 mhz c 11 54 mhz d 9 09 mhz. In a transistor colpitts oscillator c1 0 001 µf c2 0 01 µf and l 5 µh. 2n4401 npn transistor datasheet.
