Coaxial Termination refers to the process of joining the end of a coaxial cable with a resistor to stop signal reflection, usually ascribed to a 75 ohm resistor. Structure of the Coaxial Cable The Conductive Core The main element is the inner conductor of the coaxial cable. Typically, these are copper or a less expensive […]

Satellite communication antennas are high-precision devices used to send and receive geosynchronous orbit satellite signals. The gain of a typical Ka-band parabolic antenna can reach 45dBi. It uses a carbon fiber sandwich structure to achieve ±0.1mm deformation control, and completes polarization calibration (error <0.5°) and Doppler frequency offset compensation (accuracy ±10Hz) through a precision servo
