- **Caution**: 
- **Caution**: 

### Q: What is the primary function of an output buffer stage in transmitter circuits?
**A**: The output buffer stage temporarily stores and conditions the signal before transmission, ensuring proper impedance matching, signal integrity, and power handling while isolating the transmitter core from load variations.

### Q: Why are materials like GaAs and ceramic substrates used in output buffer stages?
**A**: Gallium Arsenide (GaAs) offers superior high-frequency performance for RF applications, while ceramic substrates provide excellent thermal management and electrical insulation for reliable operation in demanding electronic environments.

### Q: How does the impedance matching network improve transmitter performance?
**A**: The impedance matching network maximizes power transfer between the buffer amplifier and output connector while minimizing signal reflections, reducing losses, and improving overall transmitter efficiency and signal quality.
