LGA stands for Land Grid Array and it is used in computer motherboards to serve as the physical interface for microprocessors. It is a type of packaging for integrated circuits in which the pins are placed on sockets, unlike other forms where the pins are connected directly to the ICs. Older forms like PGAs or pin grid arrays involve pins on the microprocessor chips.
Also called a low-noise block, low-noise converter (LNC), or even low-noise downconverter (LND), the device is sometimes wrongly called a low-noise amplifier (LNA). The LNB is a combination of low-noise amplifier, frequency mixer, local oscillator and intermediate frequency (IF) amplifier. It receives the microwave signal from the satellite collected by the dish, amplifies it, and downconverts the block of frequencies to a lower block of intermediate frequencies (IF).
