RF testing above 6 GHz
The ATE RF instrumentation is generally limited to 6 GHz, whereas currently devices for satellite (> 15 GHz) and future communication require higher signal frequencies. Higher frequency measurements are still possible using 6 GHz equipment but require either up or down frequency conversion (mixing), depending on signal source or capture. This talk highlights the need for testing in the higher frequency ranges and the possibilities for measuring beyond 6 GHz. The practical hardware challenges in the development stage will be considered. The highlighted topics will be calibration, controlled impedance, source path and capture path requirements, jitter, phase noise and losses.
