## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Thermal Management
- Problem : Overheating during continuous transmission reduces reliability and performance
- Solution : Implement proper thermal vias under the package and consider heatsinking for high-duty-cycle applications
Pitfall 2: Poor RF Layout
- Problem : Signal integrity issues and performance degradation
- Solution : Maintain 50Ω impedance matching throughout RF traces and minimize parasitic inductance/capacitance
Pitfall 3: Insufficient Power Supply Decoupling
- Problem : Oscillations and spurious emissions
- Solution : Use multiple decoupling capacitors (100pF, 0.01μF, 1μF) close to supply pins
### Compatibility Issues with Other Components
RF Front-End Components:
- Compatible with : Standard 5GHz RF switches and filters with 50Ω impedance
- Potential Issues : Mismatch with components having different impedance characteristics
- Resolution : Use appropriate matching networks when interfacing with non-50Ω components
Digital Control Interfaces:
