A new design of wide band equalizer using meandering lines

Abstract

This paper reports the design of a miniaturized microwave amplitude equalizer providing a concave curve with the maximum attenuation of 5.6 dB at the center frequency 9.5GHz and 1.1dB loss at 6GHz and 2.1dB loss at 12 GHz. What's more important, it is very convenient to adjust the curve by changing the length of resonator and the value of resisters. The equalizer was analytically computed based on 3D simulation software HFSS and compared with the measured data of the real model, they match up well. The whole size of the miniaturized wide band equalizer is 30mmx17mmx11mm.
