ABSTRACT:
The invention relates to a voltage controlled analog phase shifter for operation at millimeter and microwave wavelengths using MMIC (Monolithic Microwave Integrated circuit) fabrication techniques. The phase shifter is formed of an artificial transmission line consisting of multiple unit elements in which each unit element contains a serial transmission line-inductance and a shunt diode capacitance which is variable as a function of an applied potential. In the design, the interconnecting transmission lines may be a small fraction of a wavelength, substantially less than one-quarter wavelength, and of high impedance relative to the characteristic impedance of the phase shifter. In consequence of the lumped design, each unit element, and a phase shifter using a plurality of such unit elements may be very small. The design also exhibits a low to negligible power consumption.
