« on: November 04, 2012, 03:22:58 PM »
   If you are technical ham radio (No bra bra.. ham),Outstanding data are useful for  X-Tal ladder filter designs.It is can be calculation of Lm,Cm,Rm,
Otherwise Cp measuring by component test set.(No required VNA)
10MHz X-Tal can be found in Thai market.Brand is KDSI.

My test equipment is VNA HP4195A using S21 for test .The measurement data as following.

Summary

The X-Tal Parameter as following


DUT








I hope there are useful for ladder design that the X-Tal can be found in Thai
