RF Primer

Radio Components

• Radio Waves: Electromagnetic Waves 30 Hz - 300 Ghz
• Transmitter: generates radio waves
  • Designed to work at a particular frequency
• Antenna: Propagate / receive radio waves
  • Can receive at a particular frequency
  • The bigger the antenna the further it is gonna go
• Receiver: Collect radio waves

Frequency

• Hertz: cycles per second
• 50hz "Bass tone": 50 cycles per second
• 900 Mhz: 900,000,000 cycles per second
• 2.4 Ghz: 2,400,000,000 cycles per second
• 5 Ghz: 5,000,000,000 cycles per second

Frequency Contrast

Waves

• Amplitude: The distance between the crest and the through
• Crest: The peak of the wave
• Through: The low point of the wave cycle
• Wavelength: The distance between two successive peaks
