Why is q factor important?

Answer: A coil, capacitor, or inductor’s performance in terms of losses and resonator bandwidth is measured by the Q factor. Q factor is significant when working with RF tuned circuits for a variety of reasons. Here is a list of some of these causes:

Bandwidth:

As the quality factor Q rises, the bandwidth of the tuned circuit decreases. As losses decline, the tuned circuit gets sharper because the circuit can store energy more effectively.

Phase noise in oscillators:

Phase noise produced by an oscillator causes a random shift in the signal’s phase. By increasing the Q factor, the oscillator design can be adjusted to reduce noise.
