Abstract

The transmit error vector magnitude (EVM) performance measurements of a slant-polarized 28 GHz gapwaveguidebased phased array is analyzed in this paper. The performance is studied by using a large range of signals, with varied powers, symbol rates, and quadrature amplitude modulation (QAM) orders. The measurements have been conducted for four different scanning angles. A non-standardized over-the-air (OTA) link between the phased array and the receiver in a laboratory environment is used. The results show that the phased array antenna supports a 31 dB effective isotropic radiated power (EIRP) dynamic range at a maximum 2% EVM when transmitting a 64QAMmodulated signal with 250 MS/s symbol rate at all scanning directions.
