1. A method for determining an insertion loss associated with a ferroelectric circuit component comprising:

  • fabricating a circuit comprising the ferroelectric component;

    measuring an insertion loss of the circuit;

    determining a portion of the insertion loss of the circuit that is due to loss sources other than the ferroelectric component;

    subtracting the portion due to other loss sources from the measured insertion loss of the circuit;

    determining the loss associated with the ferroelectric component; and

    recognizing, based on the determined loss associated with the ferroelectric component, that the Q of the component is higher than 100.
