10 Gbps SDH 광전송시스템을 위한 클럭보상/데이타 재생회로용 전압제어 hair-pin 공진 발진기의 설계

A design of voltage controlled hair-pin resonator oscillator for the use of clock precovery/data regeneration circuit in 10 Gbps SDH fiber optic systems

In this paper, A VCO(Voltage Controlled Oscillator) in use of clock recovery/data regeneration circuit for 10 Gbps fiber optic receivers was developed. The improved hair-pin resonator with a parallel coupled lines, which has been applied to microstrip filters, was used as a resonance part. As a frequcncy tuning device by substituting 3-terminalMESFET vaaractor for varactor diode, an MMIC manufacturing process will be simplified. Since a hair-pin resonator is planar type compared to the dielectric resonator and has a relatively flat reactance verus frequency, it will be favorable to apply a hair-pin resonator to an MMIC, in addition wideband frequency tuning range is able to be obtained.
