[0005] To achieve the above-mentioned objectives, in a first aspect, the inventor provides a handheld test terminal for the W band, comprising a handle, an antenna frequency filtering device, an oscillation frequency filtering device and a frequency mixing filtering device, wherein an antenna interface is provided at one end of the handle, and the antenna interface is used for connecting the W band antenna; the antenna frequency filtering device is installed in the handle, and the antenna frequency filtering device is used to filter and amplify the W band signal; the oscillation frequency filtering device is installed in the handle, and the oscillation frequency filtering device is used to generate and filter the oscillation frequency; the frequency mixing filtering device is installed in the handle, and the input end of the frequency mixing filtering device is respectively connected to the output end of the antenna frequency filtering device and the output end of the oscillation frequency filtering device, and the frequency mixing filtering device is used to mix and filter the W band signal filtered and amplified by the antenna frequency filtering device and the oscillation frequency filtered by the oscillation frequency filtering device, and then output them.
[0006] Different from the prior art, the technical solution of the present application is provided with an antenna interface connected to the W-band antenna on the handle, and is connected to the W-band antenna through an antenna frequency filter device, an oscillation frequency filter device, and a frequency mixing filter device, down-converting the W-band signal and outputting a 1-6GHz intermediate frequency signal, so that the W-band test can be completed using a low-frequency instrument. In addition, compared with a large test terminal, the handle-shaped handheld test terminal is smaller in size, easier to carry for testing, and has a wider range of uses.
[0007] As an implementation mode of the utility model, the handheld test terminal for W band further includes a W band antenna, and the W band antenna is connected to the handle through an antenna interface.
