Coaxial resonator, yomwe imatchedwanso dielectric resonator, mtundu watsopano wa resonator wopangidwa ndi kutayika kochepa, zida zapamwamba za dielectric zokhazikika monga barium titanate ndi titanium dioxide. Nthawi zambiri amakhala amakona anayi, cylindrical, kapena zozungulira.Zogwiritsidwa ntchito mu Band Pass Filter (BPF), Voltage Controlled Oscillator (VCO). Ukadaulo wapamwamba kwambiri wowuma wowuma komanso ukadaulo wapamwamba kwambiri umagwiritsidwa ntchito kuti ukwaniritse pafupipafupi.
