A Wide-band Front-end for DVB-H Tuner Receptions
A wide-band variable-gain LNA,RF VGA and a mixer implemented in 50GHz 0.5um SiGe BiCMOS technology for DVB-H tuner front-end is presented. The LNA uses the distribution structure with a fixed gain stage to get 20dB vanable gain and low noise. The LNA achieves 600MHz bandwidth with less than 6dB noise figure and+3-dBm of 1IP3 at max gain. The RF VGA is carefully designed to get 30dB variable gain with 5dB per step and 16-dBm IIP3 with max gain. Two mixers for I/Q signals are designed to get 22dBm of IIP3. The chip consumes 150mW power with 3.3-V supply.
