    Lost Solution with Ping-Pong mode

    • Ping-Pong mode benefit: 30% of test cost saving.

    Rich development experience for RF product

    • 2 dedicated development engineers focus on RF product
    • More than 10 years development experience on RF test.
    • Short implement cycle time(<1wk for nomal product)
    • Test time reduction: Test item/limit optimization base on test data analyzing, Test method change/wait time reduction
    • Major customer: ALP / MXD / RDA

    Rich development experience for TVS product

    • Hardware design and PCB layout.
    • 2 dedicated experienced engineers focus on TVS product development.
    • Short implement cycle time(1day for normal product after HW ready)

    Cost down solution

    Tester efficiency

    • To develop test solution on QTT / AMI to support Ping-Pong model
    • Ping-Pong mode benefit: 30% of test cost saving.
    • Major customers: AMZ / LIF / WIS

    Test time reduction

    • Test item/limit optimization base on data analyzing.
    • Test method change/wait time reduction.
    • AMZ / LIF / WIS (60ms-> 45ms)

    Sub-6GHz 5G PA/FEM test

    • Higher frequency (3.3GHz~4.9GHz)
    • Higher bandwidth (>200MHz)
    • Sub-6GHz 5G RF test solution can be worked out by upgrading our existing tester and handler within 2 months.

    mmWave test

    • Key test challenges at mmWave

    Test Method of mmWave

    • Wireless test head needed
    • Isolation box needed(upgrading handler)
    • New Tester needed(NI-STS)
