A Precise Analog Phase Shifrer for SHF SATCOM Phased Arrays[复制链接]
An analog phase shifrer for satellite on board phased.arrays is presented The compact MMIC circuit consists of a buffer amp@er and all-pass phase shift sections, covering 7 to 8.5 GHz. The RMS phase error over frequency is 21.5 degrees. The amplitude variation over phase states is 2 0.5 dB. The phase resolution is preserved by a linear control w e . Better than 80% DC and RF yield was obtained across a four inch wafer.
