    • Disclosed herein, among other things, are methods and apparatuses that provide a manufacturable RF transmission line to go through the bend area of a flexible circuit to be used in a compact design, such as in a compact hearing aid design. One aspect of the present subject matter relates to using multiple inner layers of the flexible circuit to route RF transmission. By not using outer layers, the RF transmission line will be less susceptible to delamination from the polyimide dielectric layer. One aspect of the present subject matter relates to choosing copper transmission line to have dimensions that allow for narrower transmission lines with good RF return loss. The copper transmission line dimensions also allow for manufacturing in a standard process without adding extra cost.
    • 这里公开的是提供可制造的RF传输线以通过柔性电路的弯曲区域以在紧凑设计中使用的方法和装置,例如紧凑的助听器设计。 本主题的一个方面涉及使用柔性电路的多个内层来路由RF传输。 通过不使用外层,RF传输线将不易与聚酰亚胺电介质层分层。 本主题的一个方面涉及选择铜传输线以具有允许具有良好RF回波损耗的较窄传输线的尺寸。 铜传输线尺寸也允许在标准工艺中制造而不增加额外成本。
