FAQ:
How do you assist clients with signal transition issues between RF connectors and PCBs?
- We offer more than just connectors; we provide simulation support. Our RF engineers use HFSS to help optimize the transition layout from the connector to the PCB microstrip, ensuring minimal signal reflection for your specific board material and stack-up.
Do you provide hermetic RF connectors with Pressure Windows?
- Yes. This design is developed for waveguide or coaxial systems requiring high/low-pressure differential isolation. We use high-strength sealing glass as the pressure window, maintaining high microwave signal transparency while withstanding significant pressure differences.
Can Yolanda custom-develop connectors for specialized impedance needs?
- Yes. While 50Ω is standard, we can customize impedance hermetic connectors for broadcasting or specific test systems. Our R&D team will perform new electromagnetic designs to ensure performance metrics across the entire frequency range.
