A method for manufacturing microwave dielectric ceramics has the steps of: mixing multiple A-metal compounds and sintering multiple A-metal compounds between 1350&#x2dc;1450&#xb0; C. for 2&#x2dc;4 hr to make a first component Ba(NbMn)O; mixing and sintering multiple B-metal compounds to make a second component BaNbO; and mixing the first component Ba(NbMn)O, the second component BaNbOand at least one sintering aid to make a third component (1&#x2212;x)Ba(NbMn)O-xBaNbO; wherein x, y, z and k are molar fractions and 0&#x2266;x&#x3c;1, 0&#x3c;y&#x2266;0.3, 0&#x2266;z&#x2266;0.3, 0&#x2266;k&#x2266;0.1; and the at least one sintering aid is 0.3&#x2dc;3 wt %. The microwave dielectric ceramics of (1&#x2212;x)Ba(NbMn)O-xBaNbOhave superior microwave properties, low sintering temperature, simple chemical composition and manufacturing requirements applicable to low temperature co-sintered ceramic systems so no re-tooling is required.
