Abstract :
This paper presents a Ku-band low-noise block that includes very high susceptibility to power supply PLL in a 0.18 um CMOS technology. The front-end down-converts the input signal from the Ku-band (10.5~13 GHz) to the IF (~2.3 GHz). The fully integrated LNB is dedicated to both satellite receivers and microwave link products. The VCO that includes full differential varactor shows a very low supply sensitivity (Kpss = -0.18[%/V]) that can eliminates on chip voltage regulator. The LNB performances include 28.2 dB gain, -20.5 dBm IIP3, 3.4 dB NF, and -107 dBc/Hz phase noise at 1 MHz offset. The front-end consumes 364 mW from a 1.8V supply. The core size is about 0.95×2.3 [mm2].
