The present invention discloses dielectric ceramic compositions having dielectric properties suitable for high frequency bands, such as microwave and millimetric wave, and a method for manufacturing multilayered components, such as chip LC filters, chip duplexers, and dielectric filters for PCS, using the dielectric ceramic compositions. The dielectric ceramic composition not only possesses low dielectric loss, a high dielectric constant, and temperature stability, but are also capable of being sintered at low temperatures and simultaneously baked with metal electrodes, including silver, copper, silver/palladium. Therefore, the dielectric composition can be applied to temperature stable capacitors (NPO MLCC), microwave oscillators, substrates, filters, planar antenna and on the like. The dielectric composition are represented by the general formula: A.sub.x 'A.sub.1-x "B.sub.y 'B.sub.1-y "O.sub.4 where A' and A" are La, Nd, Y and Al; B' and B" are Nb and Ta.
