Kits and Parts ADE-1 Mixer
- All Ports are 50Ω
- +7dBm Local Oscillator Injection Design
- Full Diplexer at the IF Port
- Optional Attenuators for RF & LO Ports
- Kits and Parts Mixer
- Mixer Diplexer description
- 7 MHz RF, 40 M band
- 16 MHz LO
- Si5351A square wave drive, 50 Ohm source impedance, 1.65V peak
- 9 MHz IF
Diplexor is a bandpass/band-stop filter popularized by Joe Reisert W1JR that is used after a double Balanced Mixer to provide a 50 ohm termination to all frequencies at the mixer's IF port, and to the following amplifier stage. Maintaining a consistent load at the mixer avoids overload and Inter-Modulation Distortion (IMD) effects that these mixers are prone to when not properly terminated.
