AWG50 Coax vs. AWG48 MCT [Case Study: Lumen I.D. for Cable: 1.25mm]
Smaller Dimension and Greater Transmission Property
In this case study, a transmission line for a 64ch ultrasound probe must pass through the cable lumen of a catheter with an inner diameter of 1.25mm.
For a Coax cable, the best choice utilizes AWG 50 conductors and has a 1.22mm outer diameter. A similar performing AWG 50 Junkosha MCT cable is much smaller than the Coax cable, with an outer diameter of 0.98mm.
However, a Junkosha MCT cable with AWG 48 conductors offers improved signal transmission characteristics and an outer diameter of 1.16mm, which is still smaller than the AWG 50 Coax cable. This results in both improved ultrasound image quality as well as an improved catheter assembly process.
