## 2. Design Considerations
### 2.1 Common Design Pitfalls and Solutions
#### Pitfall 1: Improper Decoupling
Problem : Inadequate power supply decoupling causing frequency instability and phase noise degradation.
Solution :
- Use 100nF ceramic capacitor placed within 2mm of power pins
- Additional 10μF bulk capacitor within 10mm for noise suppression
- Implement star-point grounding for analog and digital supplies
#### Pitfall 2: Incorrect Load Matching
Problem : Mismatched load impedance leading to frequency pulling and reduced output power.
Solution :
- Implement π-network matching for optimal 50Ω interface
- Use vector network analyzer for impedance verification
- Include trimmer capacitors for fine-tuning during prototyping
#### Pitfall 3: Thermal Management
Problem : Excessive temperature rise affecting frequency stability and long-term reliability.
Solution :
- Provide adequate copper pour for heat dissipation
- Maintain minimum 2mm clearance from heat-generating components
- Consider thermal vias for improved heat transfer to inner layers
### 2.2 Compatibility Issues with Other Components
