Background

Lnb (low noise block down konverter) is a low noise block down-converter, which is composed of a mixer and a local oscillator. LNBs can be generally divided into C-band LNBs (3.4GHZ-4.2GHZ) and KU-band LNBs (10.7GHZ-12.75 GHZ). The LNB is required to amplify the signals because the satellite total signal is relatively weak before reaching the antenna and the signal loss increases with higher frequency coaxial cable transmissions, without degrading the signal-to-noise ratio too much. The working process of the LNB is to amplify the satellite high-frequency signal, then use the local oscillation circuit to determine the intermediate frequency range according to the LNB type, convert the high-frequency satellite signal to the intermediate frequency of 950MHZ-2150MHZ and amplify again, so as to be beneficial to the transmission of the coaxial cable and the demodulation and work of the satellite receiver. The traditional LNB has the problems of large appearance volume, resource consumption, complex processing and manufacturing procedures, overhigh cost and the like, and has poorer interference resistance, so a novel amplifier product is urgently needed.
