Abstract :
A wide band phase shifter (2.1-6.4 GHz) has been made in the framework of a European program for development of standard MMICs. It makes use of eight switchable cells providing high resolution regardless of process variations and with a large choice in the phase states selection. It is implemented on two separate chips (for better flexibility) and has demonstrated, with a 7 bits control, less than 1 RMS error, a ± 0.9dB amplitude variation and an I/O VSWAR always better than -11dB at the lowest frequency.
