Kappa 438 High Frequency PCB
Hi,
Hope this email finds you well.
This RF PCB has FR-4 matched dielectric constant (Dk). The design transition to this PCB will be effortless.
 
Kappa 438 PCB
FR-4 was historically a material choice for many less demanding RF applications, but changes in the wireless infrastructure related to growing performance requirements, especially in small cells and carrier-grade Wi-Fi. However, the design transition to Kappa 438 is an effortless alternative: 
4.38 DK is tailored to FR-4 (DK 4.38) industry standard norms, which is ease of transition when upgraded electrical performance is needed over FR-4; 
(2) Tighter DK and thickness tolerance than FR-4, it keeps consistent circuit performance.
