En effet, si tu amènes le signal par un câble coaxial, et qu'il n'est pas terminé par du 50 … WebApr 15, 2016 · You can use 82 Ohms / 43 Ohms pair. Make sure resistors are suitable for high frequency. Preferably use Thin Film 0402 resistors. PCB traces must be very short. Ground plane is the must. Impedance matching for PCB traces is not an issue until total trace length between 75 Ohms input connector and MAX2015 input is below 5-7 mm.

WebJul 7, 2024 · The reason for both 50 and 75 ohms is both technical and historical. First, those two resistance values are close to the natural value that impedances have using a coaxial transmission line of convenient dimensions – the first such lines were made of copper plumbing pipe of different diameters, with one inserted into the other. WebThe 75 ohm impedance matches a dipole antenna in free space. RG (for radio guide) was originally a unit indicator for bulk radio frequency (RF) cable in the U.S. military's Joint Electronics Type Designation System. The suffix /U means for general utility use. The number 59 was assigned sequentially.
