RF Module Packaging

ALTER UK offers customers support in both prototype/process development for RF and Module packaging as well as volume manufacturing capability. By prototyping on the volume manufacturing tool-set ALTER UK can offer a risk-free transition to manufacturing with a fully optimized and high yield process. 

As RF modules run at very high frequencies the effects of capacitance and stray inductance become even more important. The RF module must be designed and assembled with an understanding of these effects.

These processes can be coupled with any of ALTER’s Packaging platforms such as plastic overmoulded QFN and Photonics packaging to provide a complete solution for your RF device.

ALTER UK’s expertise and capability in RF Module Packaging will reduce risk and reduce time to market for your laser RF module packaging requirements as well as providing a cost-effective manufacturing option.

ALTER’s RF and mm Wave test laboratory in Seville can provide testing and qualification of RF devices up to 55GHz.
