Laser Trimming of Frequency and Q-factor of Dielectric Ceramic Resonator

Abstract

A new method is presented for calculating frequency and Q-factor of dielectric resonator. The effects of etching position, dimension and shape on frequency and Q-factor are then simulated numerically. Based on the theoretical results, a novel laser trimming procedure is utilized to adjust the frequency of practical ceramics for dielectric resonators aiming better performance. Experimental results show that the resonant frequency increases after laser etching applied on either upper or lower surface of resonator; meanwhile, the Q-factor of dielectric resonator is improved
