W7ZOI Design
- A Termination Insensitive Amplifier for Bidirectional Transceivers - W7ZOI design
- Bi-directional - amplifiers in both directions
- 50 ohms in/out
- BNC or SMA Connectors
- Transformer-less
- Power applied to one half at a time - determines signal flow direction
Schematic in KiCAD
- Single channel
- With SPICE directives
- Both channels
- With SPICE directives
NGSPICE Simulation
- NGSPICE run from KiCAD
- +24 dB @12V
- Closely matches
- Across Band
CAD
