Abstract :
The authors describe the construction and fabrication of three different phase-locked oscillators (PLO) at 21 GHz. The first PLO consists of a direct division (analog and digital) from 21 GHz to the reference frequency. The second approach uses only one analog divider to reach 10.5 GHz and then a sampling phase detector. The final one consists of a 10.5-GHz MESFET dielectric resonator oscillator phase-locked by means of a sampling detector and a multiplier (by two). A comparison of analysis, fabrication, and performance of the three PLOs is presented.<>
