The PAx-ac RF PA/FEM System

The X-Series PAx-ac test system has been specifically developed to address the test challenges of advanced front end RF devices used in 4G and 5G Wireless applications which require ever more demanding RF test capabilities at a lower cost of test. The PAx-ac delivers  uncompromised RF performance in a low cost system for testing RF power Amplifiers and FEMs for next generation standards including 802.11ac, LTE and LTE-advanced.

With the PAx-ac customers benefit from the following advanced capabilities:

  • Increased UPH (units per hour) with ultra fast settling times, typically less than 1ms
  • Improved source flexibility to develop lower cost configurations and increased multisite
  • Measure frequency extension to 18GHz for third harmonic testing
  • 100 / 200MHz digital test pins for more complex and higher speed digital protocols

The PAx-ac can be configured to meet the challenging multiband standards of today and in the future. The PAx-ac provides:

    • Single-site or multi-site cost effectiveness
    • LTXC DragonRF test technology for PA  and FEMs
    • Production ready, proven capabilities
    • Leverages LTXC X-Series RF installed base
    • Minimal facility cost structure
    • Maximum production efficiency
