“…The package technology provides more pin count compared to wafer-level chip-scale package (WLCSP) with improved electrical performance because of less parasitic electrical interference [9]. The chip deploys 16 RX and 16 TX paths, which are connected to 2 × 16 PCB antenna arrays [10]. The antenna array is designed using a multilayered PCB structure, where top and bottom patches are electromagnetically coupled to achieve a broadband response.…”

This paper presents an 802.11ad-based radio frequency module for high data rate fixed wireless access and backhaul communications. The transceiver chip is manufactured in SiGe BiCMOS technology covering 57–71 GHz, providing 16 RX and 16 TX paths with combined output power of more than 20 dBm. The chip is packaged using embedded wafer-level BGA technology of the size $$12.6\times 12.6\times 0.8~{\text{ mm }}^3$$ 12.6 × 12.6 × 0.8 mm 3 and employs advanced dielectric materials with 2 metallic redistribution layers. The package integrates the transceiver chip with RX and TX high gain PCB antenna arrays, allowing effective isotropic radiated power (EIRP) of more than 40 dBm. Beam steering is achieved in ± 50$$^{\circ }$$ ∘ by the transceiver through providing appropriate weights to the antenna arrays. The paper presents generation of beamforming lookup table along with optimization of the power distribution to the array. This optimization results in flattening of the EIRP over the whole beam-steering range and frequency bandwidth. The module allows for data rates up to 10 Gbps by employing full-channel 128 QAM and half-channel 256 QAM single-carrier modulation.

“…In this system, Tx and Rx are configured using four transceivers. A narrow beam in the azimuth plane is synthesized using a 16-element uniform linear array (ULA) at both Tx and Rx [25]. The input power to each antenna element at Tx is adjusted to 0 dBm; hence, the transmit power is approximately 31 dBm in terms of equivalent isotropic radiated power (EIRP), which means a total antenna gain is 19 dBi because the beamforming gain is 12 dB.…”

“…For MPC parameter extraction, a smooth and continuous representation of each beam pattern is necessary. The beam patterns of the phased array antennas (BFM06005/06010, Sivers IMA [25], [28]) were modeled using the manifold separation technique (MST) [29].…”

Fast Double-Directional Full Azimuth Sweep Channel Sounder Using Low-Cost COTS Beamforming RF Transceivers

This paper presents a multipath component (MPC) parameter estimator that uses a double-directional (D-D) channel sounding system in WiGig millimeter-wave bands. It employs low-cost commercial-off-the-shelf (COTS) RF transceivers capable of beam steering within an azimuth angle range of ±45 • ; the transmit power is approximately 31 dBm, equivalent isotropic radiated power (EIRP), including a total antenna gain of approximately 19 dBi. The half-power beam widths in the azimuth and elevation planes are 6 • and 45 • , respectively. A fast D-D channel acquisition in 360 • full azimuth range can be achieved by developing a 4 × 4 multiple-input-multiple-output (MIMO) time division-multiplexing (TDM) scheme that enables simultaneous use of four antenna arrays at both sides of the transmitter and receiver. The beam switching for all combinations (48 × 48 = 2304) with 12 beams at each array requires less than 200 ms, excluding optional procedure related to data storage. A high-resolution MPC extraction method was developed from the D-D angular delay power spectra obtained using the sub-grid CLEAN algorithm, which is applicable when phase coherence among multiple snapshots obtained via the beam-switching measurement cannot be guaranteed. Furthermore, the operation of the developed system was validated via a measurement at 58.32 GHz in an office floor of a university laboratory. From the data analysis, the cluster properties and the corresponding scattering processes were identified.

“…The upgrade of the Large Hadron Collider for high luminosity will result in multiple times higher event rates, which demands high data rate readout systems in the order of 50 to 100 Tbps. The feasibility of 60 GHz wireless links in harsh detector environments was studied by investigating different antenna arrays at 28 and 60 GHz and performance degradation of wireless communication chips after irradiation [66,67].…”

The FREIA Laboratory at Uppsala University focuses on superconducting technology and accelerator development. It actively supports the development of the European Spallation Source, CERN, and MAX IV, among others. FREIA has developed test facilities for superconducting accelerator technology such as a double-cavity horizontal test cryostat, a vertical cryostat with a novel magnetic field compensation scheme, and a test stand for short cryomodules. Accelerating cavities have been tested in the horizontal cryostat, crab-cavities in the vertical cryostat, and cryomodules for ESS on the cryomodule test stand. High power radio-frequency amplifier prototypes based on vacuum tube technology were developed for driving spoke cavities. Solid-state amplifiers and power combiners are under development for future projects. We present the status of the FREIA Laboratory complemented with results of recent projects and future prospects.
