Abstract

This paper presents the design, simulation and characterization of an ultra-wideband microstrip gain equalizer (EQ) on thin film ceramics. The work thoroughly elaborates the design process of how to design a millimeter wave EQ, transforming a standard RF attenuator into an RF compatible gain equalizer. To reach best performance, state of the art microwave manufacturing techniques and materials like alumina, sputtered thin film resistors and laser trimming were used. The proposed design enables a simple, gain equalization slope adjustment only by setting two resistance values accordingly. It can also be adapted to other substrate materials and thicknesses as well as lower and higher frequency ranges. To verify the performance achieved in simulation, multiple samples were fabricated and measured. The measured samples exhibit ultra low measurement variance, indicating a tolerance-insensitive design and excellent manufacturing of the specimen. The manufactured EQ features a broadband operating frequency range from 60 GHz to 120 GHz, resulting in a relative bandwidth of 67%. Its excellent measured return loss of at least 15 dB and low insertion loss of 1 dB make it an excellent choice for future millimeter wave applications of up to 120 GHz and beyond.
