| Zusammenfassung: | The utility model relates to a broadband radio frequency combined-type power amplifier, which belongs to the technical field of the radio frequency circuit and comprises an amplifier consisting of N amplifier units and is characterized in that: the broadband radio frequency combined-type power amplifier further comprises a power combiner consisting of k 3dB quadrature bridges with one fourth wavelength and k loads passing through M-level cascades; and a power divider consisting of K Wilkinson in-phase broadband two-way distributors and K 90 degrees phase shifters passing through M-level cascades; M is an positive integer, N is equal to 2M and K is equal to 2M minus 1. The working bandwidth of the whole amplifier is widened. The utility model has the advantages of small size, high efficiency, easy implementation and good replicability. |
