1. A method of manufacturing an antenna-filter array module that includes at least two antenna elements on a low temperature co-fired ceramic, LTCC, tile couplable to a radio printed circuit board, PCB, in an antenna array, the method comprising:
soldering an LTCC tile having the at least two antenna elements to a first side of a module PCB, the soldering including soldering at first soldering sites lying between the LTCC tile and the module PCB, the module PCB having a size at least as great as a size of the LTCC tile;
cutting the LTCC tile into reliability issue free, RIF, units, each RIF unit having a size not greater than a predetermined largest reliable size; and
forming a plurality of second soldering sites configured to couple with the radio PCB on a second side of the module PCB opposite the first side of the module PCB.
