description The invention discloses a continuously adjustable analog phase shifter, comprising N series-connected lumped phase shift units, with N≥1, where the ith lumped phase shift unit is a high-pass lumped phase shift unit or a low-pass lumped phase shift unit, with 1≤i≤N. The invention adopts a lumped phase shift unit, and utilizes the advantage of small size of the lumped parametric circuit, thereby allowing the phase shifter to have a compact structure, small area, low cost and convenient integration. The lumped phase shift units in the invention may be selected as all high-pass lumped phase shift units or low-pass lumped phase shift units as appropriate, thereby having a flexible circuit structure that can meet the requirements at various operation frequencies. The lumped phase shift units in the invention may be selected to take the form of series-connected high-pass lumped phase shift unit and low-pass lumped phase shift unit, thereby permitting a wider bandwidth.
