First check DC biasing conditions
VCE = 50% of VCC that is 50%of 10V = 5Volt
VCB= 40%VCC
VBE=10%VCC
It is an LC oscillator hence its output frequency will be very high
Use IFT secondary side as the inductor and two 0.001 micro Farad ceramic disc capacitor (code 102)
Colpitt’s oscillator is also an LC oscillator. The tank circuit is made up of C1, C2 and L. R1, R2 andRE
provide self bias for the transistor. Capacitors C1 and C2 act as an ac voltage divider and produce
180O phase shift. A further phase shift of 180O is provided by the CE amplifier. In this way proper
feedback is supplied to produce continuous undamped oscillations.
