Inputs

Outputs

EXAMPLE:

  • INPUTS:
    • Input frequency range = 800 (low) to 850 MHz (high)
    • Local Oscillator Frequency = 700 MHz
  • OUTPUTS:
    • Output Lower sideband = 100 (low) to 150 MHz (high)
    • Output Upper sideband = 1500 (low) to 1550 MHz (high)

RF Mixer Formula/Equation

The core principle of an RF mixer is to combine two input signals (RF and LO) to produce output signals at the sum and difference of their frequencies. The image below illustrates the basic formula.
