This letter presents a convenient approach based on the two-port kQ-product theory to analyze the influence of interwinding capacitive coupling on the efficiency of the transformer. It is demonstrated that a transformer with proper size can benefit from the interwinding capacitiv

This letter presents a millimeter-wave
(mm-wave) vector-modulated phase shifter (VMPS) for phased-array applications.
To improve the phase-shift accuracy without drastically increasing design
complexity, the proposed VMPS structure employs variable-gain amplifiers (VGAs)
that off

Digital beamforming receivers (RXs) support MIMO operation and offer great flexibility and accuracy in multi-beam formation and calibration. However, compared with analog phased-array and hybrid systems, due to the absence of any rejection for spatial in-band blockers, the RX/ADC
