FIELD OF THE DESCRIBED EMBODIMENTS

The described embodiments relate generally to wireless communications. More particularly, the described embodiments relate to systems, methods, and apparatuses for a housing structure for maintaining alignment between ceramic sections of a ceramic filter.

BACKGROUND

High-performance bandpass filters are needed for wireless communication devices.

It is desirable to have methods, apparatuses, and systems for a housing structure for maintaining alignment between ceramic sections of a ceramic filter.

SUMMARY

An embodiment includes a housing structure. The housing structure includes an L-shaped outer structure, a plurality of flexure portions, wherein at least one of flexure portion extends from an end portion of each of extended arms of the L-shaped outer structure, wherein each flexure portion extends inward perpendicular to each of the extended end portion, and a plurality of reference datums, wherein at least one reference datum is located between an L-joint of the L-shaped outer structure, and a one of the flexure portions. The housing structure operates to receive a plurality of sections of a waveguide filter, wherein each section includes a plurality of planar surfaces, wherein the datums and the flexure portions are operative to maintain alignment of the sections of the waveguide filter relative to each other when the plurality of sections of the waveguide filter are inserted within the housing structure.

Another embodiment includes a remote radio unit (RRU). The RRU including one or more antennas, a downlink bandpass filter, and an uplink filter, wherein both the downlink bandpass filter and the uplink filter connected to the one or more antennas. At least one of the downlink bandpass filter and the uplink filter includes housing structure, the housing structure includes an L-shaped outer structure, a plurality of flexure portions, wherein at least one of flexure portion extends from an end portion of each of extended arms of the L-shaped outer structure, wherein each flexure portion extends inward perpendicular to each of the end portions, a plurality of reference datums, wherein at least one reference datum is located between an L-joint of the L-shaped outer structure, and a one of the flexure portions, and the housing structure operative to receive a plurality of sections of a waveguide filter, wherein each section includes a plurality of planar surfaces, wherein the datums and the flexure portions are operative to maintain alignment of the sections of the waveguide filter relative to each other when the plurality of sections of the waveguide filter are inserted within the housing structure.

Other aspects and advantages of the described embodiments will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the described embodiments.
