The utility model discloses a low-insertion-loss broadband transmission type microwave phase shifter capable of being tuned in a full-frequency and full-period mode. The device is composed of a microwave circulator (C), a microwave transmission line (T), a center conductor (D), a total reflection probe (P), a probe driving device (M), a load (L), a shell (B) and the like, a third microwave connector (C3) in three ports of the microwave circulator is connected to one end of the microwave transmission line (T) through the center conductor (D), and the total reflection probe is arranged in the microwave transmission line and is in complete conductive contact with the center conductor. The probe driving device drives the total reflection probe to move along the central conductor to realize phase shift, and the load (L) is connected to the other end of the microwave transmission line through the other end of the central conductor. A reflection type phase shifter is converted into a transmission type phase shifter
