Microwave Transmission System

Microwave Spectrum:

Range is approximately 1 GHz to 40 GHz

Total of all usable frequencies under 1 GHz gives a reference on the capacity of in the microwave range
Components of a Microwave System:

1) Digital Modem.

2) Radio Frequency (RF) Unit.

3) Antenna.
Digital Modem:

The digital modem modulates the information signal.

(intermediate frequency or IF)

RF Unit:

IF is fed to the RF unit which is mounted as close physically to the antenna as possible.

(direct connect is optimal)

Waveguides:
Waveguides are hollow channels of low-loss material used to direct the signal from the RF unit to the antenna.
