Comparison between ferrite and diode phase shifters to be used in phased-array antennas
Abstract
A survey is given of the properties of the nonreciprocal latched remanent ferrite phase shifter and of the diode phase shifter in microstrip. A comparison is made between these two types at 3 GHz where items which are important for use in phased array antennas are used as a yardstick. The deviating results at lower and higher frequencies are mentioned separately. Other types of ferrite and diode phase shifters are also discussed. The possibilities of realizing phase shifters at millimeter wavelengths are mentioned. An indication of very recent and expected future trends is given. Some remarks on cost are made.
