(1) Suppose that L= 65nH, c= 47pF and Rloss measured = 0.01 ohm, then the impedance of the tuned circuit = (XL+Rloss)// XC?? is it true????Zout is difficult, its theoreticaly the impedance of the tuned circuit ( L/CRloss) in parallel with the output impedance of the transistor.
What if I use a transformer like this:The trouble is that as you match the 50 ohms to the transistor, you loose gain so you can have a perfect match but no oscillations. I would just use a 1/2 turn link of thick wire wound around the non-collector end of the coil.
Look in the manual for .net commands.
Also look on the internet for this PDF ( LTspice_4_e2.pdf) . Great intro , and more advanced stuff for LTSpice.
I'm not going to attach as it's too big.
The S11 and Zin point is meaningless for the present circuit, at least regarding antenna matching, because it's an oscillator and has a RF-wise input short.
In the list of traces you can add to the plot is Zout. Look through carefully. As mentioned above Zin / S11 is not really of any use here.
