- Description
- A Low Noise Amplifier (LNA) is an integral component within a satellite telecommunications receiver system that acts to boost weak incoming signals while limiting the amount of additional noise introduced. Its is used for signal reception via satellite where its main purpose is to perform initial amplification in the second block of the receiver system (immediately behind the antenna), amplifying the faint radio frequency (RF) signals captured by an Aerial/Antenna before further onward processing. The Low Noise amplifier comprises of electronic components and Integrated circuit boards housed in a metal casing with power supply circuitry. The incoming power feed to the amplifier is generally DC and comes from a remote rack mount unit via a cable assembly. The amplifier is a critical part of a satellite telecommunications “system” which is used for communications over commercial frequency satellites. The “system” provides voice and data connectivity to radio frequency (RF) networks. The telecommunications system comprises of a satellite antenna, transmit or receive amplifier, frequency converter and cabling to both power source and signal transmission beyond RF. The amplifier amplifies radio frequency (RF) signals and serves to both filter noise and aid signal quality for signals received from satellite to earth. Interface connectors include: DC Power: RF Input and RF Output Electro-mechanical assembly. Electronic components and circuit boards are housed in a metal chassis or casing. For shipment the units are packaged in purpose designed timber cases with protective packaging material.

- Justification
- Classification has been determined in accordance with the following: For the purposes of determining the commodity codes within which goods most appropriately fall, reg 3 (1) of The Customs Tariff (Establishment) (EU Exit) Regulations 2020 sets out that the rules of interpretation contained in the following have effect – a. Part Two (Goods Classification Table Rules of Interpretation) of the Tariff of the United Kingdom (Reg 3(1)(a)); and b. Notes to a section or chapter of the Goods Classification Table (Reg 3(1)(b)). GIR 1 - Has been used to classify this product by the terms of heading 8543 - Electrical machines and apparatus, having individual functions, not specified or included elsewhere in this chapter GIR 5 (b) - has been used to identify the type of packaging. GIR 6 - Has been used to classify the goods to subheading level 8543 70 - Other machines and apparatus 8 Digit Code 854370 30 - Amplifier, consisting of active and passive elements mounted on a printed circuit, contained in a housing Also Classified in Accordance with: Harmonized System Explanatory Notes (HSENs) (9) to Heading 8543 - High or intermediate frequency amplifiers (including measurement amplifiers and aerial amplifiers).
