Balanced mixing circuit composed of two double-gate field effect transistors
Source: InternetPublisher:fish001 Keywords: Field effect transistor gate mixing circuit field effect transistor Updated: 2021/05/26
Shown is a balanced mixing circuit composed of two double-gate field effect transistors . The radio frequency signal couples the signal to the gate of the field effect transistor through the input transformer Tl . The local oscillation signal is added to the other two gates
of the field effect transistor through the coupling transformer Tz. The drain of the field effect transistor (VT1, VT2) The pole output is passed through the intermediate frequency transformer (IFT), and the signal output with an intermediate frequency of 10.7 MHz is selected.
