Analysis and translation of product requirements into electrical specifications, PCB layouts, simulation, confirming design choices through prototyping.

RF/Microwave modeling and simulation, along with component-level and circuit-level design, test, troubleshooting.

The full life-cycle development, from fundamental design phase to proof of concept prototyping through all the way to product production.

design

rf design questions in order for your project:

→ Type of Service & Application?
→ Operating environment? (Temperature, humidity, viabration, radiation, etc.)
→ How will your product be used? (Stationary/moving, sea/aerial/space, etc.)
→ What information to be sent? (Voice/video/data or combination of the three)
→ How will your product be powered? (Battery/AC)
→ How large is the product should be? (Size, weight)
→ Product technical parameters requirement? (Specification)
→ Available spectrum or frequency?
→ Required design time frame?

architecture
