The invention discloses a capacitor-loaded type phase shifting filter. The capacitor-loaded type phase shifting filter consists of a digital phase shifter WYD and a filter. By adoption of a low temperature co-fired ceramic technology, the digital phase shifter is integrated on the filter to realize functions. The capacitor-loaded type phase shifting filter with high phase shifting precision, relatively low insertion loss, excellent electrical performance, stable temperature performance and novel structure is realized, and can be applied to occasions and corresponding systems having strict requirements on volume, eletricla performance, temperature stability and reliability of radar, electronic warfare and the like.
