Like all universal LNB's, this LNB receives the 10.7-11.7Ghz and 11.7-12.75Ghz Ku bands and looks like a normal single output universal LNB. But inside it hides two characteristics that make this LNB "special". For one thing, this is a PLL LNB. PLL LNB's, as I explained in my previous post, have much higher frequency stability than the more common DRO LNB's. This makes them specially suited to receive low symbol rate transponders. Marketing claims this LNB has an NF of 0.4 dB, 58 dB gain, 25 dB of cross polar discrimination and current consumption between 80-120mA. Sharp BS1K1EL100A PLL LNB To my knowledge this was the first mass market LNB with PLL technology. According to Sharp this is the first LNB in the world with a unique SoC (System on Chip) that integrates in a single IC the mixer, IF, amplification, PLL and LO. Also according to Sharp, this technology allows decreasing the Noise Figure and increasing the Gain linearity. The two local oscillator frequencies needed to receive the full Ku band are generated from a 25Mhz crystal. Inside the IC this 25Mhz frequency is multiplied by 390 (for 9.75Ghz low band) and 424 (for 10.6Ghz high band).
