Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] The structure of the six-way power splitter with reconfigurable number of power splitters in this embodiment is shown in the attached figure 2 As shown, the circuit is implemented using a Rogers 6002 dielectric substrate with a loss tangent of 0.0012 and a thickness of 0.38 mm. SPMT switches and SPST switches can be implemented using PIN diodes. When the excitation is balanced, the signal with a center frequency of 0.8GHz is fed from the signal input terminal Port 0 on the upper surface of the dielectric substrate, and through the input exponential gradient impedance matching line, the signal enters the specified λ / 4 by controlling the working state of the PIN diode. The impedance converter and the corresponding transmission branch are finally transmitted to the signal output terminal to realize the function of equal power distribution...

The invention relates to a multi-path power divider with a reconfigurable number of power division paths. The multi-path power divider comprises a metal micro-strip layer, a dielectric substrate and a metal grounding plate, the metal micro-strip layer is arranged on the upper surface of the dielectric substrate, and the metal grounding plate is arranged on the lower surface of the dielectric substrate. The multi-path reconfigurable power divider comprises a signal input end, a single-pole multi-throw switch, a parallel lambda / 4 impedance converter, an output transmission branch, a star-shaped isolation network and a signal output end. According to the multi-path reconfigurable power divider, by switching the single-pole multi-throw switch and selecting different transmission paths, the number of power division paths can be reconfigurable, and the reconfigurable power divider is ensured to have high isolation, good port matching and amplitude-phase consistency. The power divider aims to improve circuit performance and an integration level, reduce equipment design and manufacturing cost and realize the miniaturization of communication equipment, is suitable for a miniaturized multi-path power synthesis system, and has a wide application prospect in a microwave communication system of a reconfigurable technology.
Description
technical field [0001] The invention relates to a multi-channel power splitter with reconfigurable number of power splits. Background technique [0002] A power splitter, also known as a power divider, is a common microwave multi-port device, mainly used for signal power distribution and synthesis, and is widely used in mixers, amplifiers and other devices, as well as wireless communication systems such as phase-controlled radars. Currently commonly used power splitter types mainly include T-type power splitters, Wilkinson power splitters, and Gysel power splitters. In recent years, with the rapid development of wireless communication systems, people not only require the communication system to have the characteristics of large capacity, high speed and low delay, but also increase the demand for miniaturization, low power consumption, and multi-function of the communication system. The complex structure and single function of the system obviously cannot meet people's needs....
