A Fully Integrated Broadband Direct-Conversion receiver RFIC for Satellite Tuner

摘要：

This paper presents the circuit design and measured performance of a wideband receiver for direct conversion satellite tuner. The tuner RFIC is composed of a wideband front-end,a baseband low pass filter with on-chip automatic tuning circuit and a full integrated fractional-N synthesizer. A DC offset cancellation loop is also integrated without the use of external capacitors. The chip draws 140mA current from a 3.3V power supply. It achieves a sensitivity of 78dBm for 3/4 coding QPSK signal with 28.8MS/s symbol rate and 6.9dB C/N.It is fabricated in a 0.35-μM siGe BiCMOS technology and occupies a silicon area of 3.1 mm2.
