## 2. Design Considerations
### 2.1 Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Power Supply Decoupling
- Problem: RF noise coupling into power rails causing signal degradation
- Solution: Implement three-stage filtering: 10µF tantalum + 1µF ceramic + 100nF ceramic placed within 5mm of VDD pins
Pitfall 2: Improper Antenna Matching
- Problem: High VSWR (>2:1) reducing effective radiated power
- Solution: Use π-network matching with variable capacitors for fine-tuning during prototyping
Pitfall 3: Thermal Management Neglect
- Problem: Extended transmission periods causing thermal shutdown
- Solution: Provide 15mm² copper pour on PCB connected to thermal pad with 4-6 thermal vias
Pitfall 4: Clock Signal Integrity Issues
- Problem: Reference clock jitter exceeding 50ps causing frequency drift
- Solution: Use dedicated oscillator with <20ppm stability, keep
