Abstract :
A novel technique to extend the phasing range of the vector sum phase shifter by exploiting its second order response is proposed and implemented. A continuously variable phase shift is demonstrated between 8 and 16 GHz with phasing range exceeding 450° measured at 16 GHz. Good agreement between the predictions and measurements has been obtained.
