Hi,All
I want to build a oscillator,in order to get very high Quanlity-factor&very high freqency.
So i decide to use SAW resonator.
The datasheet recommend the circuit below.
I have some idears totally different with the datasheet
I think here in the circuit there is no effect of the SAW.i don't know what role it plays a Capactor,a Inductor or a pure Resistor,in my opinion i think the circuit will oscillate too without the SAW,the frequency is determined by L1,C1,C2,~~~~~,it's a classic Colpitts oscillator~~~~
In order to prove my opinion i simulate the circuit(without SAW)in pspice,it works well~~~~~~~
But the circuit (with SAW) is the one in the datasheet,so i don't think the manufacturer will give us a foolish circuit,
So~~~How the SAW work in this circuit below??
Thanks
