    We provide an end-to-end RF antenna testing service

    The testing parameters for passive antennas
    Once the antenna is integrated into the device, we will provide the necessary parameters to define and quantify any antenna:
    Impedance
    VSWR (Voltage Standing Wave Ratio)
    Return Loss
    Efficiency
    Peak/Gain
    Average Gain
    2D Radiation Pattern
    3D Radiation Pattern

    Total Radiated Power (TRP)
    TRP provides the power radiated when the antenna is connected to the transmitter. These measurements are applicable to devices of various technologies: LTE, 4G, 3G, WCDMA, GSM, and HSDPA.

    Total Isotropic Sensitivity (TIS)
    TIS parameter is a critical value as it depends on antenna efficiency, receiver sensitivity, and self-interference.

    Radiated Spurious Emissions (RSE)
    RSE is the emission of a frequency or frequencies outside the necessary bandwidth. Spurious emissions include harmonics, parasitic, intermodulation, and frequency conversion products, but do not include out-of-band emissions. Our RSE reduces spurious emissions to avoid affecting other surrounding devices.

  • Approval Testing

    +
    Full market access solutions including pre-compliance testing, product testing, documentation services, and product certification.

  • Mass Manufacturing

    +
    We provide an end-to-end manufacturing process. Our company conducts internal manufacturing processes, strictly adhering to the IATF16949:2016 Certificate and ISO9001 standards. The production process involves customized manufacturing techniques for shell material injection molding, welding, riveting, injection molding, ultrasonic processes, and more. Additionally, for PCBA, we have designed SMT assembly lines. Furthermore, an essential aspect of our production process is the strict adherence to SOP for product testing, including the use of network analyzers to test for standing waves and other parameters.

  • Antenna Integration Guideline

    +
    We assist in integrating antennas into devices, whether it's during the design phase or as part of the final product.
