Title:
可変電力分割器
Document Type and Number:
Japanese Patent JP2006506013
Kind Code:
A
Abstract:
A variable power divider and method can vary the RF power between ports in a high power and multi-carrier RF environment, such as is used in controlling signals sent and received in a base station antenna. The variable power divider can include a single-control phase shifter and a hybrid power divider. The single-control phase shifter can comprise a three-port device having a single input port and two output ports. The single-control phase shifter can further comprise a variable adjuster that can change or adjust the phase between two RF signals. The hybrid power divider can comprise a four-port device having two input ports and two output ports. Both the single-control phase shifter and the hybrid power divider can comprise substantially planar structures that are suitable for high-speed manufacturing. The output ports of the hybrid power divider can be coupled to various devices such antennas or power absorbing elements.
