A 7-Bit Vector-Sum Phase Shifter for LEO Satellite Communication in 90-Nm CMOS Process

A 7-Bit Vector-Sum Phase Shifter for LEO Satellite Communication in 90-Nm CMOS Process

This paper presents a 7-bit vector-sum phase shifter for low-earth-orbit satellite communication. The phase shifter consists of a differential-type quadrature all-pass filter (QAF) and an analog differential vector adder, where a matching network is inserted between the QAF and vector adder to minim...
