Four channel, ultra-high-capacity transceiver module

When starting to work with this FAAMG technology giant, the HAPS market was still embryonic. We were approached, not to quicken the market but to change the market, to redesign what’s possible. These unique challenges were all about performance, the client wanted a paradigm shift in performance level. Customised to meet their mechanical interface, the heatsink was defined by the client, but we integrated the multiplexer into their mechanical architecture, reducing weight, footprint & component count.


The solution

  • Collaborated very closely with our client’s engineering team
  • Integration into clients airborne & ground mechanical requirements.
  • Development included 4 channels, each channel capable of 10Gbps, resulting in a 40Gbps point-to-point link.

The result

Filtronic solution
Ground to air comms link
  • World record at the time of 40Gbps development, ground to air communication link.
  • Highly integrated solution with all 4 channels integrated to optimise size, weight and power.
  • Solution delivered was at 71-76 & 81-86 GHz frequency bands.

The challenge

  • How do you push the boundaries not iteratively but create a step change.
  • Performance change by an order of magnitude of 40x
  • Minimise power consumption through careful circuit design and performance choices.
  • Development of communications backhaul links that deliver sufficient bandwidth and range to provide ultra-high-capacity wireless connectivity.
  • Included compact, high-power amplifier modules to meet long-range requirements.
