ADMV4640 Overview
The ADMV4640 is a microwave downconverter optimized for various satellite munication (SAT) user terminals operating in the 10.7 GHz to 12.7 GHz RF range. The ADMV4640 local oscillator (LO) signal is generated internally via the on-chip Integer N (INT) synthesizer. The internal synthesizer enables LO frequency coverage from 8.7 GHz to 10.7GHz.
