Impedance spectra of $\mathrm{Ag_2HgI_4}$ and $\mathrm{Ag_2CdI_4}$ ternary superionic compounds have been experimentally measured in a wide frequency/temperature range. Low- and high-frequency ionic transport mechanisms have been clearly identified via equivalent circuit analysis. Temperature behaviors of the ohmic parameters are discussed for both compounds. Equivalent circuit type at higher frequencies is defined by the microcrystalline structure of the investigated materials.
