Broadband high-pass phase regulator

Abstract

The invention relates to a wideband high pass phase regulator in the electronic technology field, wherein the second microstrip line is connected with the input end, and the other end of the second microstrip line is connected with the anode of the second variode and is connected with one end of the fourth microstrip line, the other end of which is connected with the ground; the cathode of the second variode is respectively connected with the cathode of the first variode and one end of the first microstrip line. The first variode and the second variode adopt the back-to-back connecting method, wherein the first microstrip line with one end of the direct supply and the two capacitances, and the other end of which is connected with the ground. The anode of the first variode is respectively connected with one end of the third microstrip line and the fifth microstrip line, and the other end of which is connected with the ground, and the output end of the third microstrip line is connected with the output. The invention has simple structure and easy realization, which obtains the frequency response with wider band and the larger phase adjustment degree, applied in the wideband voltage controlled oscillator and the power amplifier.

Description

technical field [0001] The invention relates to a phase adjuster in the field of electronic technology, in particular to a broadband high-pass phase adjuster. Background technique [0002] With the development of radio frequency and microwave integrated circuits and systems, phase regulators are widely used in various radio frequency circuit systems, such as voltage-controlled oscillators and power amplifiers. In the communication system, due to the wide use of the phase-locked loop circuit, the frequency in the system is required to be tuned, so the phase adjuster is widely used in the voltage-controlled oscillator, and the phase in the oscillator can be effectively adjusted by changing the voltage, thereby To achieve the purpose of adjustable narrowband frequency, and this method will not reduce the phase noise. [0003] After searching the literature of the prior art, it was found that Yong-Sheng Dai et al. published in "IEEE Microwave and Wireless Components Letters", (...

Problems solved by technology

Its disadvantage is that although this design method increases the bandwidth of the phase adjuster to a certain extent and improves its tunable range, its loss also increases correspondingly, which is about 2.5-3.5dB; in addition, due to the lack of research and design methods Certainty and particularity, this method is difficult to form a certain design rule, and the circuit is relatively complicated, so it is difficult to implement
