Abstract

The embodiment of the invention discloses a balanced-unbalanced filter-divider. The balanced-unbalanced filter-divider comprises a rectangular branch structure defined by 5, 6, 7 and 8, four open circuit transmission lines (9, 10, 11 and 12) connected to the four vertices of the rectangular branch structure respectively, two subcircuit transmission lines (13 and 14) connected to the rectangular branch structure, an isolation transmission line (15), an isolation resistor (16), two balanced input transmission lines (2 and 4) and two non-balanced output transmission lines (1 and 3). The balanced-unbalanced filter-divider not only has a filtering function and a common-mode rejection function, but also has the advantages of being simple in structure, small in size, high in technology tolerability and low in cost.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to a balanced-unbalanced filter power divider. Background technique [0002] The full name of the power divider is a power divider, which is an energy device that divides the energy of one input signal into two or more outputs that are equal or unequal. According to the number of outputs, the power divider is usually divided into one divided into two, one divided into three and one divided into six. The main technical parameters of the power splitter are power loss (including insertion loss, distribution loss and reflection loss), voltage standing wave ratio of each port, isolation between power distribution ports, amplitude balance, phase balance, power capacity and frequency band width etc. [0003] Nowadays, with the rapid development of radio frequency technology, balanced power splitters are widely used because of their advantages such as convenient connection with o...
