| Abstract: | It is presented that the theory and the manufacturing technology of such analog phase shifter,which are made from conventional 3 dB 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-20 dB,insertion loss 4.8 dB(including 3 dB attenuator),transmission difference less than±0.075 dB.Computer code PHASES.bas can present the referenced component values. |
