RFSW200 RF switch box system is introduced. In the current industry, when testing multi-port components, manual plugging and unplugging of loads or RF coaxial cables are used, which takes a lot of time. RFSW200 is a multi-port component that requires interactive measurement between any two ports. For example, base station antennas, base station filters, cable TV distributors, network transformers … and other multi-port component test equipment, the RFSW200 successfully established the following key technologies by overcoming various technical difficulties.
- Technology to reduce the number of calibrations: In the multi-port component test, if any two ports need to be calibrated, the number of dual-port calibrations is very large, such as a 12-port base station antenna, if any two ports need to be calibrated, a total of 66 dual-port calibrations are required , And Melgen electronic technology only needs to do 6 dual-port calibrations to measure the S-parameter between any two ports. Using this technology, the measured data is compared with the measured value of the network component. The error is about 0.1dB. This technology Realize the dream of multi-port automatic measurement.
- Long-term measurement stability after calibration: Many multi-port devices from manufacturers in the industry have problems with the measurement curve drifting shortly after calibration, and the 12-hour graphics measured by RFSW200 are still consistent , meeting the demand for stable testing time in the factory.
- The untested port load requires a return loss of more than 30dB: RFSW200 provides a complete correction calculation technology for non-30dB return loss loads, which perfectly solves this measurement problem.
