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.

Key Features		Applications/Uses
Low-Cost Architecture Operates from Single +5V Supply On-Chip Quadrature Generator, Dual-Modulus Prescaler (/32, /33) Input Levels: -20dBm to -70dBm per Carrier Over 50dB RF Gain-Control Range 10dB Noise Figure at Maximum Gain +8dBm IIP3 at Minimum Gain		Broadband Systems Cell Phone Base Stations DirecTV, PrimeStar, EchoStar DBS Tuners DVB-Compliant DBS Tuners LMDS Microwave Links Wireless Local Loop (WLL)
