Wireless (RF) fundametals

Learned From Agilent RF Training Course

1. RF circuit design is all about keeping things in phase!
2. Physical dimensions are critical to RF performance!
3. A second unique aspect of RF design is that physical construction affects
   Electrical Performance.
4. Linearity = universal applicability linearity = complexity + cost +
   Current
5. Much of the system design is about making the proper trades among four
   Variables:

• Frequency
  (Broadcast frequencies:
  Regulatory Agencies | internal frequencies: available components, cost,
  Performance)
• Signal
  Strength
  (Output power vs. battery life, safety, government regulations,
  Cost)
• Coding
  
  (Standards, interoperability, recovery of recovery -- microprocessor)
• Modulation
  Scheme
  (Standards; interoperability, recovery of recovery -- microprocessor +
  Radio influences linerity requirements of Radio)
