This article presents a 23.5-29.5-GHz 8x8 phased array for wideband multistandard applications. The array is based on wideband high-performance 2 x 2 transmit/receive (TRX) quad-beamformer chips with 6 bit of phase control and 8 bit of gain control. The antenna is designed using a stacked-patch structure combined with a two-stage impedance matching network to enhance its bandwidth. The 8 x 8 phased array achieves an effective isotropic radiated power (EIRP) of 54.8 dBm at P1dB with a 3-dB bandwidth of 23.5-30.5 GHz and can scan to +/- 60 degrees in the azimuth plane and +/40 degrees in the elevation plane with excellent patterns with a single-point calibration at 27 GHz. Measured error vector magnitude (EVM) for a 64-QAM 200 and 800-Mbaud waveforms result in a system EVM of 5% (-26 dB) in the TX mode at an average EIRP of 46-47 dBm at 24.5-29.5 GHz. Also, the wideband array is capable of 16-QAM 24-Gb/s links with an EVM
