19-1449; Rev 0; 4/99 Direct-Conversion Tuner IC General Description The MAX2108 is a low-cost direct-conversion tuner IC designed for use in digital direct-broadcast satellite (DBS) television set-top box units and microwave links. Its direct-conversion architecture reduces system cost compared to devices with IF-based architectures. The MAX2108 directly tunes L-band signals to baseband using a broadband I/Q downconverter. The operating frequency range spans from 950MHz to 2150MHz. The IC includes a low-noise amplifier (LNA) with gain control, two downconverter mixers with output buffers, a 90° quadrature generator, and a divide-by 32/33 prescaler.
