摘要

In this work, we designed 94-GHz 4× 4 Butler matrix circuits in glass-based integrated-passive-device (IPD) technology. Given the design rule constraints, the inevitable crossover structure is carefully planned as a miniature low-pass filter carrying simulated 0.2 dB insertion loss, successfully incorporating parasitics with good matching. The fabricated standard Butler circuit exhibits insertion loss of 8 dB, with mismatch less than 1 dB and phase difference less than 10 degrees at 94 GHz. Size reduced by 34%, the miniaturized circuit shows insertion loss about 1 dB worse but phase mismatch improved by 3 degrees. The core areas of the standard and miniaturized circuits are 1.42× 1.22 mm2 and 1.04× 1.08 mm2, respectively. The designs are applicable to beamforming phased arrays in the W band.
