Abstract :
A single chip direct conversion DVB-H tuner with a distortion compensated variable gain LNA is implemented in 0.5mum SiGe BiCMOS. The LNA exhibits 0dBm IIP3 and 2.8dB NF at 860MHz. A new offset cancel feedback is introduced that keeps the cutoff frequency independent of the baseband gain. The IC consumes 184mW at 2.8V while achieving a sensitivity of -96dBm for QPSK, CR=1/2 signal
