MAX2116
Description
The MAX2116/MAX2118 family of low-cost directconversion tuner ICs are designed for use in digital direct broadcast satellite (DBS) television applications, professional VSAT systems, and two-way Internet through satellite applications. These devices set the standard for integration and performance, significantly reducing the required RF know-how for design implementation. Uniquely architected, the MAX2116/MAX2118 simplify direct main board and tuner module designs. The MAX2116/MAX2118 devices directly convert Lband signals to baseband using a broadband I/Q downconverter. The operating frequency range extends from 925MHz to 2175MHz. Each IC includes an LNA with gain control, I and Q downconverting mixers, and baseband lowpass filters gain and cutoff frequency control. Together, the RF and baseband variable gain amplifiers provide more than 79d B of gain control range. The devices include fully monolithic VCOs, as well as a plete frequency synthesizer. Additionally, an onchip...
