摘要：
A novel single (Bode mixer with ultra high LO/RF, LOAF isolation and having a reasonably good conversion loss has been designed. RF and LO signals are applied through bandpass and lowpass filters respectively. The mixer operates in C-Band and downconverts a block of frequencies (5.925GRz - 6.425GHz) to a block of frequencies (3.7GHz - 4.2GHz) using a fixed frequency local oscillator at 2.225GHz. The proposed mixer structure achieves double balanced functionality with a single diode and obviates the need for RF and LO baluns. The measured conversion loss ranges from 8 - 10dB and port isolations are in excess of 60dB.
