| Zusammenfassung: | Digital phase shifter, comprising series connection of controlled phase shifting bits ( 3 a- 3 k), each of them inserts determinate amount of phase delay of the passing signal, wherein the phase change occur in response to the control signal switching the phase cells 3 k and applied to its steering terminal 4 k for a switching element ( 11, 21, 22, 31, 32 ) of each of the cells 3, characterized in applying as a switching element ( 11,21,22,31,32 ) the discrete p-HEMT (pseudomorphic high electron mobility transistors) with positive or negative pinch-off voltage. |
