Abstract
Aspects of a method and system for a multi-band direct conversion complementary metal-oxide-semiconductor (CMOS) mobile television tuner are provided. A single-chip multi-band radio frequency (RF) receiver in a mobile terminal comprising UHF and L-band front-ends receives and amplifies an RF signal utilizing a low noise amplifier (LNA) an LNA integrated into the front-end that corresponds to the type of signal received. A received signal strength indicator (RSSI) value may be determined for the amplified signal within the receiver and may be utilized to adjust a gain of the LNA. The adjustment may be made via on-chip or off-chip processing of the RSSI value. The receiver may directly convert the amplified signal to a baseband frequency signal and generate in-phase and quadrature components. The components of the baseband frequency signal may be filtered and/or amplified via programmable devices within the receiver. Circuitry within the receiver may be controller via an on-chip digital interface.
