1.0 GENERAL INFORMATION
1.1 System Overview
The MA4040D is a modular circuit card, designed for use with the WaveCom MA4000D Series. Each MA4002D
card chassis with common MA4011D (or MA4012D) power/control module can contain up to 10 - MA4040D
independent frequency agile upconverters in a 4U (7”) rack mount configuration. In addition to front panel control,
each MA4002D chassis is also fully remote controllable via a serial RS232 /RS485 Interface or optional integral
SNMP agent.

1.2 Functional Overview
The MA4040D is a fully agile commercial quality IF upconverter for cable, MMDS (Multichannel Multipoint
Distribution System) and LMDS (Local Multipoint Distribution System) applications. The MA4040D also allows
broadband data products to establish an RF channel and create a virtual bus topology on a coaxial backbone.
Advanced design allows a single MA4040D card to cover a frequency band from 53 to 857 MHz, and maintain a
phase noise specification that exceeds the DOCSIS requirements for 64/256 QAM. Remarkably low out of band
noise performance and low spurious are achieved through high level mixing, a microwave frequency IF and multiple
levels of filtering. This advanced, cost effective upconverter offers high performance, flexibility and space efficiency.
Redundancy features make it suitable for the most demanding applications.
