| Abstract: |
| The design of high LO-rejection for Ku band receiver front-end is described. The
leakage approach of high frequency LO signal is summarized and analysed. Corres
ponding designs of structure and circuits are optimized and high rejection of le
akage signal is realized. The max value of LO-rejection of the developed Ku band
receiver front-end is 96 dBc. The test results of 5 samples indicate the effect
iveness of analysis and design. |
