AN INTEGRATED LOW-NOISE BLOCK DOWNCONVERTERIn this paper, a small-sized low-noise integrated block downconverter (LNB) used for Ku-band direct reception from broadcasting satellites (DBS) is proposed. The operating frequency of the LNB is from 11.7 to 12.2GHz. The outlook dimension is 41 X 41 X 110mm^3. Measured results show that the average gain of the LNB is 57dB, and noise figures are less than 1.7dB. It has been found that clear TV pictures have been received using the LNB for the experiment of receiving the "BS-2b" (Japanese broadcasting satellite) at Harbin region, Heilongjiang Province, P. R. China.
