Abstract :
The design, fabrication and performance of an L-band 4-bit GaAs MMIC phase shifter are described. It exhibits low RMS phase error (<1.8 degrees), good VSWR (<1.5), and low insertion loss variation (4.91±0.35 dB) for all sixteen phase states over the entire operational bandwidth in the 1.0-1.2 GHz frequency range
