Abstract :
An attractive means to reduce the complexity of the radio-frequency hardware is obtained by direct modulation. An alternative architecture of a direct vector modulator is described, working over the ETSI 15 GHz band realised using a subharmonic mixer. It includes on-board phase tuning for correcting the quadrature phase error.
