Transmitter Test: Overcoming Five Fundamental Challenges
Application Notes
The development of any wireless system is a demanding task, bounded by tight constraints and complicated by innumerable tradeoffs. Success in the marketplace depends on constant improvement in performance, cost, and time-to-market. Whether you’re testing components, subsystems, or complete radios, you’ll face tough challenges in RF testing. This application note offers solutions that will help you overcome five major challenges:
- Ensuring compliance with complex standards
- Making accurate RF power measurements
- Solving interference problems
- Finding and fixing EMI problems
- Optimizing power consumption
Ensuring Compliance with Complex Standards and Regulations
Mobile data and voice services have a constant need for increased channel capacity, and the same is generally true for wireless LAN. Developers are meeting these needs using a variety of techniques, each of which makes transmitter testing more challenging. Examples of these techniques include complex modulation types, frame structures, and multiplexing schemes. Multi-carrier schemes and multi-channel extensions such as MIMO and carrier aggregation only add to the complexity.
