Overview

Description: When our customer asked us to help them design an outdoor pole-mount WiMAX® Beamformer product, we jumped at the chance! This involved design was made possible by designing and connecting four unique circuit card assemblies, and a large pole-mount conduction cooled chassis. The complex electronics relied on several Xilinx® FPGAs, a Freescale® processor, multiple -48V isolated converters, a great deal of analog circuitry, including ADCs and DACs, RF circuitry (2.5 and 3.5GHz), and high-speed serial links.

One of the trickiest and most elegant solutions Fidus offered in this design was the RF connection block that allowed multiple SMP RF connectors to blindmate directly to the antenna array.
