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