PAx Test System

Market Leading Test System for High Volume RF PA / FEM, <4G, 5G sub-8.5 GHz, Wi-Fi 6/6E/7 and mmWave

PAx test system delivers uncompromised RF performance in a low-cost system for testing RF power amplifiers and front-end modules for next-generation wireless standards.

PAx’s flexible architecture allows configurations of a wide range of instruments that are designed to address the test challenges for RF power amplifiers and front-end modules used in cellular and connectivity applications, including WLAN standards up to Wi-Fi 6/6E/7, <4G to 5G sub-8.5 GHz wireless, and beyond, Bluetooth and a variety of IoT standards. Many of these new generation wireless devices require ever more demanding RF test capabilities from test instruments, such as wider bandwidths and lower EVM, and PAx’s configurable architecture delivers the optimized test solution with superior RF performance at an uncompromised cost of test.
