  • 본 논문에서는 초광대역 특성을 보이는 직렬 분포형 증폭기(Cascaded single stage distributed amplifier)에 대하여 기술한다. 직렬 분포형 증폭기는 다단 증폭기 중 하나인 분포형 증폭기(Distributed amplifier)보다는 높은 이득을 얻을 수 있다. 본 논문에서는 분포형 증폭기에 대한 간단한 이론을 설명한 뒤 직렬 분포형 증폭기에 대한 이론을 기술하고 실제 구현하여 측정을 결과를 제시한다.

  • In this paper, a broadband Microwave Power Module(MPM) operating at 7 - 11 GHz is designed and fabricated. The MPM consists of a SSA (Solid State Amplifier) and a conventional TWT (traveling Wave Tube). This combined module takes advantage of a low noise and high gain of SSA. The computer modeling and simulation of the SSA are designed by the use of the ADS (Advanced Design System) software. The SSA is designed by configurating the CSSDA (Cascaded Single Stage Distributed Amplifier). The broadband MPM is measured to be noise figure 8.3 - 10.02 dB at 7 - 11 GHz bandwidth, output power of 38.12 dBm at 9 GHz.
