RF and Microwave

Alter Technology (formerly Optocap), offers customers support in both prototype/process development for RF Module packaging as well as volume manufacturing capability.

By prototyping on the volume manufacturing tool-set Alter Technology UK can offer a risk-free transition to manufacturing with a fully optimised and high yield process.

RF Module Packaging

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.

Photonic Packaging

A key function of an optoelectronic device is to manipulate light. As a result, the packaging and assembly processes for many optoelectronic components can be significantly more complex than traditional microelectronic devices.

Optoelectronic or Photonics packaging requires extremely accurate placement of components to ensure appropriate suitable alignment and coupling of light into and out of devices. In many cases the generation or detection of light results in significant heat being generated, which if not suitably dissipated through appropriate joining technology and material selection, can adversely affect the device operation. Additionally, assembly processes can be complicated by the requirement that fluxes and other organic materials can’t be used as they can degrade the performance of facets in optical devices.

Alter Technology UK has experience in the assembly and packaging of a wide range of Optoelectronic devices including;

• High power laser diodes
• PV Cells
• Optical Interconnects
• DFB’s, SOA’s
• Mach-Zender Interferometers
• Modulators
• Photodetectors
• TOSA/ROSA’s
