The invention belongs to the technical field of power distributors and discloses a reconfigurable power divider with the double adjustment of the frequency and the power division ratio. The reconfigurable power divider comprises a dielectric substrate, a floor, a micro-strip transmission line, a short-circuit adjustable branch knot, an impedance tuning branch knot and an isolation resistor. Afterthe splitting at an input port, the input port is connected with the quarter-wavelength micro-strip transmission line with the two ends thereof connected with the short-circuit adjustable branch knotsin parallel and then connected with the impedance tuning branch knot in parallel. The working frequency and the power dividing ratio are jointly adjusted through the short-circuit adjustable branch knot and the impedance tuning branch knot. Compared with the prior art, the working frequency and the power division ratio of the power divider can be reconstructed at the same time. Therefore, the power divider can be widely applied to a phased array radar system and a reconfigurable antenna system. The result of the simulation shows that, the power division ratio of the power divider is continuously adjustable from 2: 1 to 10: 1, within the frequency-adjustable section of 0. 9GHz to 1.2 GHz.
Description
Technical field [0001] The invention belongs to the technical field of power dividers, and in particular relates to a reconfigurable power divider with dual adjustable frequency and power division ratio. Background technique [0002] Power divider, full name power divider, divides a radio frequency signal into equal or unequal two or multiple output signal energy; power divider is an indispensable component for radar and antenna array feed networks. According to the number of channels, the power divider can be divided into two channels, three channels and four channels, and multiple channels realized by cascading; according to the ratio of energy distribution, it can be divided into: equal power divider and unequal power divider According to the type of transmission line, it can be divided into: waveguide power divider, stripline power divider and microstrip power divider. The main technical parameters of the power splitter are return loss, insertion loss and bandwidth. With th...
