A Tier-1 US wireless operator requested the following extra-low PIM products (≤ -165 dBc) to for their 5G RF Lab in the Pacific Northwest:
Two months later we received our first feedback from the Lab Manager. The products worked well, but the size was too big for their lab space. They requested a diplexer that was as small as possible with 4.3-10 connectors, and they also wanted to be able to fit an extra attenuator into a 3U track on top of the existing three.
Within two weeks we delivered the size reduction that the customer requested. For the diplexer, the only difference in performance with the previous (larger) design is the small increase of insertion loss from 0.25 dB to 0.5 dB. For the attenuator, there is no difference in performance. To complement the new design, we also designed a new 19” 3U rackmount shelf that holds four ATA-Pa10R attenuators.

Our new designs were well-received, but an additional request came: “Could you prevent the heat from all units from flowing up to the top attenuators when they are stacked on shelves?” the customer asked. This was a big concern with their current manufacturer as the upper units would overheat constantly. One solution was to look at a tray fan that would blow from the bottom.
However, this was not necessary: our team had already designed and tested the units to operate safely without a fan or forced air. We informed the client that yes, we could place ATA-Pa10R Attenuators in twelve, fully loaded stacked 3U shelves (for a total of 12 x 4 = 48 attenuators) without fans, and the attenuators in the top shelf will work just fine without additional parts.
The feedback was well received and the units were implemented into a final design within those two weeks.
