A double balance mixer based on the microstrip balun is proposed in this paper. The new design is simulated and validated by the measurement. The measured results show that the typical conversion loss is 10dB from 2GHz to 20GHz, with a local oscillator (LO) power level of 12dBm. Furthermore, the return loss and the LO-to-RF isolations are better than 10dB and 20dB, respectively. Compared with the reported works, the circuit performs the best conversion loss and isolation characteristic in the wide bandwidth. In conclusion, the designed mixer exhibits an outstanding comprehensive performance. |
