Abstract

The invention discloses a phase balancing method based on dispersion characteristics of a voltage-controlled phase shifter. The phase balancing method comprises the steps of: firstly, randomly selecting a branch from a synthesis network as a reference branch; secondly, acquiring a change curve of each branch phase with a frequency by a vector network analyzer, and performing normalization; and finally, and adjusting the voltage of each branch by a voltage-controlled phase shifter and a digital phase shifter so as to enable change curves of phases of each branch with the frequency to be coincided with a change curve of the phase of the reference branch with the frequency and further to achieve phase balancing of each branch. By the phase balancing method, continuous change of a compensationphase is realized through continuous adjustment of a voltage controlled by the voltage-controlled phase shifter so as to match with phase differences, caused by time delay, of each branch in the synthesis network relative to the reference branch, the phase balancing period is short, the efficiency is high, no extra system size is increased, and the integration degree is high.

Description

technical field

[0001] The invention relates to a phase balancing method based on the dispersion characteristics of an electric phase shifter, and belongs to the field of high-power synthetic microwave amplifiers. Background technique

[0002] In microwave and millimeter wave application systems, the power of the system determines the operating distance, anti-interference ability and communication quality of the entire system. The output power of a single power device is still limited, so power combining techniques of multiple semiconductor solid-state devices or vacuum devices have been proposed to realize high-power amplifier components.

[0003] In addition to power, the bandwidth characteristics of the amplifier components are also important system concerns. Broadband microwave power synthesis technology can be widely used in electronic countermeasure equipment such as frequency agility, active array radar, radar false target, false target transponder and jamming transm...
