A 0.2 mu m SiGe BiCMOS tuner for digital satellite audio radio applications was realized using a second-zero-IF dual conversion architecture with autonomous RF AGC and channel decoder controlled IF AGC. A single PLL drives both RF and IF mixers, resulting in a smaller die area and lower power dissipation. Providing a baseband I/Q output further reduces receiver's power due to a lower ADC and digital core operating frequency. SDARS tuner performance includes: 5dB noise figure. 55dB image rejection, -96dBm input sensitivity. 100mA current from a 3.3V supply and 12min(2) die area.
