Design and Implementation of an Analog High Power Broadband Self Interference Canceller for In Band Full Duplex
… cancellation. The system is designed as a vector modulator using off-the-shelf hybrid couplers and switches with a custom variable attenuator designed using PIN diodes in a Waugh attenuator architecture. The system was fabricated on a four layer PCB and measured with a network analyzer. …

Design and implementation of a broadband RF-DAC transmitter for wireless communications
… a circuit implementation of an RF-DAC based I/Q vector modulator has been conducted and is thoroughly discussed. The RF-DAC has a resolution of 9bit and a maximum sampling rate of 850 MHz. A novel RF-DAC implementation allows especially high output power levels and at the same time a low power …

Vector modulators for analog-beamforming receivers
… particularly attractive. Analog-beamformers use vector modulators (VMs) to phase-shift and scale the amplitudes of the signals from each antenna before signal combining. These VMs require accurate phase and gain control and high DR to achieve accurate beamforming and avoid corruption of the …
