KEYCOM provides solutions for specific applications including permittivity measurement, absorption ratio, transmission tracks and devices, antennas, cables and ESR instruments for the infrasonic/VHF/UHF/microwave/millimeter-wave/super-high frequency ranges.

    KEYCOM develops and manufactures highly accurate and dependable measurement components, devices and systems in the 1 μHz-300 GHz (infrasonic / VHF / UHF / microwave / millimeter wave / super-high) frequency range by leveraging its experience and expertise accumulated over a long period of time in the field of advanced technologies.

    We can provide both measuring services and systems, depending on the application.


    Radar Systems:

    KEYCOM develops various radars for versatile applications based on its knowledge and expertise on millimeter wave and microwave technologies. KEYCOM’s product line of radars includes Radar Test Systems (RTS) to evaluate distance accuracy or output, Radar Alignment Systems (RAS) to help you adjust the alignment of radars, and Radar Cross Section (RCS) measurement systems to measure RCS of such radar targets as aircraft, ships and automobiles.


    KEYCOM’s product line includes the Radar Test System (RTS) that measures radar distance accuracy and transmission power, and the Radar Alignment System (RAS) that assists you to adjust the mounting position of the in-vehicle radar.

  • Radar Test System – 24GHz, 76.5GHz, 79GHz (RTS)ME7220A

    Active Target Simulator for  Collision Avoidance Radar

    KEYCOM’s ME7220A is a multifunctional radar test system that allows you to verify the radar measurement accuracy of the distance and speed indoors. It interfaces with spectrum analyzer and power meter for frequency and power measurements respectively. (2~3GHz for 24GHz and 76.5GHz system, 6~12GHz for 79GHz system)


    Model No.Frequency rangeBandwidth
    ME7220A-24G24 ~ 25GHz300MHz
    ME7220A-24G-1124 ~ 29GHz5GHz
    ME7220A-76G76 ~ 77GHz500MHz
    ME7220A-79G76 ~ 81GHz5GHz


    KEYCOM’s RTS is suitable for Research and Development, Radar Module Manufacturing, and Vehicle Manufacturing.

    Research and Development-

    ·Allows adjustments of distance, speed and output indoors when developing radar
    ·Fully characterizes the radar module by quantifying transmitter, receiver and antenna performance
    ·Built-in laser allows accurate alignment of the radar-under-test to the RTS antennas without additional mechanical fixtures

    Radar Module Manufacturing-

    ·Integrates into standard production lines or automated radar test stations for complete testing of the radar modules
    ·Allows full or sample testing of all critical radar parameters accurately and repeatedly in a confined and controlled environment
    ·Interfaces with external test accessories including spectrum analyzers and power meters for complete test flexibility
    ·Easily controlled from an external computer or by using the included handheld manual controller

    Vehicle Manufacturing-

    ·Verifies operation under realistic conditions by simulating moving targets (other vehicles or roadside objects) at multiple target distances
    ·Characterizes both radar transmitter and receiver performance
    ·Integrates with moving target simulator for expansion of complex testing conditions including
    changing distance between cars, changing lanes or multiple target tracking.
