    Abstract:

    This paper presents an adjustable equalizer based on spiral resonance structure, which realize miniaturization of equalizer design by increasing its equivalent capacitance and inductance under same circumstances compared with traditional single resonance structure. At the same time, three notch resonance units are designed for adjustable equilibrium quantity applied by wire bonding technique. An example of equalizer design is provided, which operates at 2–8 GHz and consists of three notch resonance units. CLTE-LC plate is applied, with 0.254 mm of thickness. The whole size of the equalizer is 20 mm×15 mm×0.254 mm. Simulation results indicate that the return losses are less than -15 dB in band, and three adjustable equilibrium quantities are achieved which are 1.8 dB,3.6 dB,5.4 dB respectively.
