Abstract: It is presented that the theory and the manufacturing technology of such analog phase shifter, which are made from conventional 3dB quadrature hybrids coupler with two identical varactor-diode networks to provide a shifted phase that varies continuously with biased DC voltage. Several analog phase shifters have been made for different operating frequencies. Each phase shifter has phase range more than 180°, return loss better than-20dB, insertion loss 4.8dB(including 3dB attenuator), transmission difference less than±0.075 dB.Computer code PHASES. bas can present the referenced component values.

Key words: analog phase shifter, 3dB directional coupler, network analyzer
