Title: Describe the function of a Low Noise Block Downconverter (LNBD).
Course: Telecommunications II (10006-II) > Section: Examining Digital Telephones

Description should include

- the components that make up the LNBD, including low-noise amplifier, frequency mixer, local oscillator, and 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:

- What components make up an LNBD?
- What is the function of each component of the LNBD?
- 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 telecommunications satellite communication?
