A Study on the Design and Implementation of SDLA for C-Band Application
C-Band용 SDLA의 설계 및 구현에 관한 연구
Abstract
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.
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,
