| 摘要 |
The invention relates to a double balanced diode mixer (10) in which an input transformer (20) is replaced by an equivalent circuit (50) which approximates the functionality of the input transformer (20). The circuit includes an LCR network (50) which filters an input RF message signal and further includes a portion which approximates a functionality of transformer to provide RF differential output signals (61, 62) for transfer to a diode ring (21).
