General Desc ription
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 base-
band using a broadband I/Q downconverter. The oper-
ating 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.
