## 2. Design Considerations
### Common Design Pitfalls and Solutions
Antenna Design Issues:
- Pitfall : Poor antenna matching leading to reduced range and performance
- Solution : Use TI-recommended antenna designs and perform proper impedance matching (50Ω)
Power Supply Problems:
- Pitfall : Inadequate decoupling causing RF performance degradation
- Solution : Implement proper power supply filtering with multiple capacitor values (100nF, 1μF, 10μF)
Crystal Oscillator Stability:
- Pitfall : Incorrect crystal loading capacitors causing frequency drift
- Solution : Use 32MHz crystal with recommended load capacitance (12-16pF) and follow layout guidelines
### Compatibility Issues with Other Components
RF Front-End Compatibility:
- Power Amplifiers : Compatible with CC2591/CC2592 range extenders for increased output power
- Antenna Switches : Ensure proper biasing and control timing for external RF switches
- Sensors : I²C, SPI, and UART interfaces compatible with most digital sensors
Power Management:
- Voltage Regulators : Requires stable 2.0-3.6V supply; LDOs with low noise output recommended
- Battery Management : Compatible with various battery chemistries (Li-ion, alkaline, etc.)
### PCB Layout Recommendations
RF Section Layout:
- Keep RF traces as short as possible with controlled 50Ω impedance
- Use ground planes beneath RF components and traces
- Maintain adequate clearance between RF section and digital circuits
Power Distribution:
- Implement star-point grounding for analog and digital sections
- Place
