Description
【Technical field】
[0001] The invention belongs to the field of electronic devices, and relates to a wide stop band reconfigurable filter type power divider based on SIR and DGS structures, which can be used in wireless communication systems such as communication and radar. 【Background technique】
[0002] With the rapid development of radio frequency / microwave circuits, the requirements for the integration, miniaturization and multi-frequency characteristics of devices are getting higher and higher. Therefore, the research and design of reconfigurable (reconfigurable frequency, bandwidth, etc.) power splitters with integrated filtering functions have attracted more and more attention. A power splitter is a microwave device that can distribute an input signal to two or more output ports according to a certain ratio, and its function is to realize the power distribution of the signal. There are many implementation forms of multifunctional power splitters, such as: power splitt...
