## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Management Issues
- Pitfall : Inadequate decoupling causing voltage drops during transmission
- Solution : Implement proper power supply sequencing and use multiple decoupling capacitors (10µF, 1µF, 100nF, 10nF)
RF Performance Problems
- Pitfall : Poor antenna design leading to reduced range
- Solution : Use TI-recommended reference designs and perform proper impedance matching (50Ω)
Timing and Synchronization
- Pitfall : Incorrect crystal oscillator loading causing frequency drift
- Solution : Use 32MHz crystal with recommended load capacitors (12-22pF) and follow layout guidelines
### Compatibility Issues with Other Components
RF Front-End Components
