Integrated UHF Receiver for Environmental Nano Satellites

Run reference : S13C15_1 - IC STMicroelectronics 130nm CMOS 6 ML HCMOS9GP (datasheet)


The analogue front-end consists of a four-stage Low Noise Amplifier (LNA), whose final stage also acts as a single-ended to differential converter circuit. There are also In-phase and Quadrature active mixers and an Integer-N Phase Locked Loop (PLL) which generates the LO signal @ 420 MHz, followed by a quadrature generator circuit based on CML logic.
