The invention discloses a hybrid broadband high-precision phase shifter integrated circuit, which belongs to the technical field of radio frequency integrated circuits. , a broadband quadrature signal generator, a quadrant selection unit and a transformer are cascaded. Among them, the π-type L-C phase shifting unit realizes 5.625° and 11.25° phase shifting states, two switch type phase shifting units realize 22.5° and 45° phase shifting states respectively, and the quadrature signal generator is used to synthesize a pair of quadrature differential Signal, the quadrant selection unit switches the positive and negative polarity of the quadrature signal to achieve a 360° phase shift range. Compared with the traditional switching phase shifter, the hybrid phase shifter of the present invention has the advantages of wide band, low insertion loss, high precision and the like.
Description
technical field [0001] The invention relates to the field of radio frequency integrated circuits, in particular to a hybrid broadband high-precision phase shifter integrated circuit. Background technique [0002] The phase shifter is the core module in the analog phased array system, and the broadband high-precision phase shift is also a difficult point in the design of the phased array transceiver chip. The phase of the traditional switch-type phase shifter depends on the frequency, and it is difficult to guarantee the phase shift accuracy at the edge of the frequency band, and it is difficult to meet the design requirements of a broadband high-precision phase shifter. At high frequencies such as the Ka band, larger insertion losses require additional amplifiers to compensate for the gain. Therefore, compared to active structures, chips with integrated passive phase shifters do not have a significant advantage in total power consumption. Contents of the invention [0003...
