“…In VM operation, it can provide 32dB amplitude control that can be used for interference cancellation. The power consumption of the IF-Rx can still be considered as low because it would be in-front of a very large sub-array, which in not the case of [3]and [5].…”

“…Local oscillator (LO) phase shifting for scalable arrays increase the buffering and LO routing at mmWave resulting in significant area and highpower consumption [3]. In [4] and [5], I/Q is generated separately at mmW or at very high IF for each element which is less accurate and requires dedicated I/Q signal generation which increase the area of chip.…”

Large-scale phased arrays need to combine weighted signals from multiple sub-arrays either in analog or in digital domain. Sub-arrays are preferably implemented modularly with integrated circuits placed next to the associated antennas. In order to enable flexible and scalable combining networks of several mmWave sub-arrays, this paper presents a wideband receiver module that provides the cartesian combining of beamforming weights for one sub-array at IF. Furthermore, it allows interference cancellation between subarrays or combining multiple sub-arrays. It also provides filtering before ADCs to support current and foreseeable 5G channel bandwidths up to 800MHz. The receiver is operating at 2-4GHz IF frequency range and has more than 400MHz baseband bandwidth, a noise-figure of 5.5dB,-6dBm 1dB compression point and +3dBm in-band IIP3. In addition, overthe-air measurements are performed, showing 26dB of interference cancellation between the sub-arrays. The prototype is implemented using 45nm CMOS PDSOI.
