mmWAVE ANTENNA-FILTER MODULE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18536773 titled 'mmWAVE ANTENNA-FILTER MODULE

Simplified Explanation

The abstract describes a method of manufacturing an antenna-filter array module using low temperature co-fired ceramic (LTCC) technology. The module PCB is bonded to the LTCC tile containing antennas and filters, with the CTE of the module PCB matching that of the radio PCB. The LTCC tile is then cut into smaller reliability units for improved reliability.

  • Explanation of the patent/innovation:
 * Manufacturing method for antenna-filter array module
 * Use of LTCC technology for antennas and filters

The abstract does not mention any potential challenges or limitations that may arise from implementing LTCC technology in the manufacturing process.


Original Abstract Submitted

An antenna-filter array module and method of manufacturing an antenna-filter array module are provided. One method of manufacturing includes 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. The method further includes 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.
