Claim 10:
11. A method of manufacturing an antenna-filter array module configured to be coupled to a radio printed circuit board, PCB, the antenna-filter array module having a module PCB having a first side on which a first set of solder balls are positioned and a having a second side on which a second set of solder balls are positioned, the method comprising:
bonding a low temperature co-fired ceramic, LTCC, tile having a plurality of antennas and corresponding filters to a first side of the module PCB via a first set of solder balls, a coefficient of thermal expansion, CTE, of the module PCB being within a predetermined amount of a CTE of the radio PCB; and
cutting the LTCC tile into a plurality of reliability units after the bonding, each reliability unit having a size that is less than a predetermined largest reliable size.
