A direct-conversion receiver for DVB-H

A fully integrated low-power ultrahigh-frequency (UHF) tuner integrated circuit (IC) design for the digital video broadcasting-handheld (DVB-H) market is presented. A direct-conversion receiver is chosen over classical digital video broadcasting-terrestrial (DVB-T) architectures. The tuner IC covers UHF bands IV/V. The solution is based on a radio frequency integrated circuit (RFIC) and external low-noise amplifier (LNA) to meet the noise figure (NF) specification of 5 dB, IIP3 of 4dBm, and Gain of 89 dB. The IC includes an LNA, dual quadrature mixers, multiple bandwidth baseband (BB) filtering, three 4X voltage-controlled oscillators (VCOs), integer phase-locked loop (PLL), and reference oscillator. The design is implemented in a SiGe:C bipolar complementary metal oxide semiconductor (BiCMOS) technology and the die area is 11.5 mm/sup 2/.
