SYSTEM DESCRIPTION
The Frequency Agile QAM Upconverter (Wavecom Electronics Inc. MA4040D) is a commercial
quality IF upconverter designed for cable, MMDS and LMDS applications.  The MA4040D
upconverter operates from 53 to 857 MHz and maintains a phase noise specification that exceeds
the DOCSIS requirements for 64 QAM.  The MA4040D is a modular circuit card and operates in
a card chassis (MA4002D)with a common power/control module (MA4011D) and can contain
up to ten (10) MA4040D independent frequency agile upconverters.
The MA4040D functions as the IF to UHF upconverter component of the BTS-7010 system.  The
MA4040D inputs the 44 MHz IF from the WMTS and output a 222 – 408 MHz output signal
that is fed to the input of the BTS-7010.
