| 摘要 |
A double balanced dual-quad transformer dual field effect transistor (FET) mixer is disclosed using a first and second (FET) which have their gates electrically connected together, such that the first and second FET are connected in series. The mixer achieves improved isolation by using a first and second diplexer, and an RF and IF coupling network which comprises a flux-coupled IF transformer and a transmission line RF balun. |
