Broadband Amplifier Gain Slope Equalization Filter

摘要：

Since the achievable gain of transistors typically falls off as the frequency increases, an equalization filter with positive gain slope is necessary to compensate for the gain roll-off of broadband amplifiers. This paper proposed an novel equalizer structure and design a equal-ization filter by applying this novel structure and a modified SIW-PBG (Substrate Intergrated Waveguide-Photon BandGap) filter. The numerical simulated results show that the proposed design of Gain Slope Equalization Filter has a positive gain slope from 8.5 GHz to 18.5 GHz with good impedance matching,low excess loss, and good selectivity.
