C-Band용 SDLA의 설계 및 구현에 관한 연구
A Study on the Design and Implementation of SDLA for C-Band Application
초록
본 논문에서는 레이다 및 EW수신시스템에서 사용하는 SDLA를 5-7㎓(C-Band)의 RF 주파수대에서 설계 구현하였다. 구현한 SDLA의 특성은 -80㏈m-0㏈m의 동작범위를 얻었고,
In this paper, the design of the successive detection logarithmic amplifier(SDLA) is reviewed for radar and EW system, and implemented in hybrid MIC. The SDLA operates over the 5 to 7㎓ frequency range. the unit has a dynamic range of -80㏈m to 0㏈m, a logging accuracy of ±1.4㏈, a legging slope 19.2㎷/㏈, and a gain flatness of ± 1.2㏈. Input VSWR of less than 2, noise figure of 2㏈, video impedance of 900Ω and output voltage range of 0 to 1.53V DC have been obtained over 80㏈ of dynamic range.
