Technology to build our wireless future

We push boundaries through innovative design, manufacturing and integration, starting with the fundamental building blocks of any RF system: passive components and packaging.


Any RF system can be broken down into two essential types of component: actives and passives. Actives are the power players, creating, amplifying, and modulating RF signals. Passives are the backbone, used to create antennas, filters, couplers, and transmission lines — everything needed to make a device truly wireless.

Ideally we would integrate active and passive components in a single technology and use that for everything. There’s just one problem: cutting-edge semiconductor tech comes at steep prices with high RF losses, making it tough to blend in passive elements. This stands in the way of the standard system-on-chip (SoC) designs ruling today’s wireless scene.

We have chips capable of propelling us to 100 GHz and beyond, laying the groundwork for our wireless future. The missing piece is a scalable approach to constructing RF systems that effectively harness the power of these chips.

SoC is DEAD. Long live SiP.

Our solution to this fundamental problem is simple: split the actives and passives into different technologies and adopt system-in-package (SiP) architectures. By moving functionality from the chip to a high-performance package we can create systems that beat SoC’s on several fronts:

  • Improved RF, mechanical and thermal performance
  • Higher efficiency through reduced RF loss
  • Lower cost, as the chips can be made simpler

The outcome? A sleek, seamlessly integrated system that outshines SoCs in performance and price.

This concept isn’t groundbreaking, but our packaging technology is. That’s our secret to crafting systems that genuinely excel.

Looking Backwards to Go Forwards

In the past, generating RF signals was a challenging task, demanding systems that utilized every milliwatt of power. As technology advanced, producing high-power RF signals became simpler, and the stringent need for efficiency diminished with the abundance of power.

The development of 5G/mm-wave and the impending shift to 6G and sub-THz have reignited the importance of efficiency. In an era where transistors yield only microwatts of power, optimizing the efficiency of our RF systems has become crucial once again.

We’re turning back to the fundamental principles, where RF power is treated as a valued asset. Our focus is on pioneering a new wave of packaging technology that prioritizes maximum efficiency, ensuring our RF systems are primed for tomorrow’s demands.
