| Abstract: |
| The design and implementation of a Ka - band hybrid integrated sub - harmonic image - rejection mixer is presented. The mixer is fabricated by using HMIC process based on the thin film ceramic sub- strate. The test results show that conversion loss is less than 11.2dB and the image - rejection ratio is more than 20dB over 4GHz RF bandwidth, when IF is fixed at 70 MHz . |
