New Method for Millimeter-Wave Signal High Sensitivity Receiving and Testing in Range

X. Chen and J. Z. Xu
Abstract—Based on the actual demand of the weak signal (low to -128 dBm) detection in millimeter-wave range test, and through the analysis of signal-to-noise ratio, the W-band receiver system of -128 dBm sensitivity is achieved by using the technology of super-heterodyne broadband multi-channel fast swept-frequency composite channelization. With the designed millimeter-wave calibration source and the spatial attenuation theory, a new test method of the high sensitivity (-128 dBm) in W-band is put forward. Theoretical analysis shows that the minimum power of the millimeter-wave signal source can reach -128 dBm in W-band when the test distance is 290 m and the corresponding attenuation value is about -121.5 dB. The practical measurements using the calibrated millimeter-wave signal source demonstrate the feasibility of the proposed test method.

Index Terms—Range test, high sensitivity, millimeter-wave source, spatial attenuation, weak signal, W-band, signal to noise interference ratio.
