MAX2116开发板套件编程器的射频评估开发套件开发板规格书PDF中文资料

General Description

The MAX2116/MAX2118 family of low-cost direct conversion 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 L band signals to baseband using a broadband I/Q downconverter. The operating frequency range extends from 850MHz 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 79dB of gain control range.
