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