This paper presents a multi-standard fully connected hybrid beamforming (FC-HBF) receiver
that can be reconfigured between two fully connected two-stream multi-input-multi-output …

This article describes system and circuit design techniques to enhance power efficiency and
incorporate new features in millimeter-wave multi-input-multi-output (MIMO) transceivers …

This letter presents a new circuit topology for a vector sum phase shifter where the
amplitudes and phases of and are simultaneously varied using a single analog control …

This paper presents a compact differential quadrature generation scheme using transformer
coupled resonators for use in scalable fifth-generation (5G) phased-array architectures. A …

In this paper, a calibration approach based on transfer function extraction for the Cartesian
vector modulator (VM) is presented. Three kinds of VM models-the ideal VM model, the …

Compared to current single-standard radio solutions, multi-standard radio transceivers
enable higher integration, backward compatibility and save power, area and cost. The …
