Low cost ferroelectric phase shifter for a higher microwave power level
New requirements are formulated for phase shifters used in phased-array antennas: 1) small power in biasing networks, 2) higher microwave power, 3) low production cost. Reflection type phase shifters on ferroelectric tunable capacitors in combination with hybrid junction form a transmission type phase shifter. Two ferroelectric capacitors are connected in parallel with respect to RF voltage and in series with respect to dc bias. Such a scheme provides > 10 W for each reflection type phase shifter, eliminating the cross modulation of the signals.
