Title: Describe the function of a Low Noise Block Downconverter (LNBD).
Course: Telecommunications I (10006-I) > Section: Examining Satellite Communication

Description should include

- the components that make up the LNBD, including low-noise amplifier, frequency mixer, local oscillator, and intermediate frequency (IF) amplifier
- the function of each component that makes up the LNBD
- the location of and physical description of the LNBD
- the role of polarization in the transmission of satellite signals.

Process/Skill Questions:

- Why is the LNBD located behind the antenna feedhorn?
- What is the difference between horizontal/vertical polarization and circular polarization?
- How is polarization used in satellite communication?
