1.0 GENERAL INFORMATION

1.1 System Overview

The MA4061B is a fully agile commercial quality IF upconverter for MMDS and LMDS applications. Advanced

design permits full frequency agility over the 2500 to 2686 MHz frequency band while still maintaining a phase

noise specification which exceeds the requirement of 64 QAM. The MA4061B is a modular circuit card

designed for use with the WaveCom MA4000 Series. The MA4070B is a solid state, fixed gain power

amplifier for MMDS applications. Each MA4000 card chassis with common MA4010 power supply can contain

up to 2 MA4061B independent frequency agile upconverters, and complementing MA4070B Power Amps in a

4U rack mount configuration. Up to 10 MA4061B’s can also be configured in a MA4000 chassis. This

advanced cost effective upconverter offers high performance, flexibility and space efficiency.

1.2 MA4061B Module Features

• Front panel selectable output frequency from 2500 to 2686 in 62.5 kHz steps

• RF output muted when changing output configuration or phase lock alarm

• High reliability, state of the art design using microstrip MMIC and surface mount technology; conservative

component derating and 100% burn in help ensure reliable operation

• Low power consumption

• Input IF AGC ensures very stable output level, even if input varies

1.3 MA4070B Module Features

• FCC emission mask approved for 31.5 dBm RF output

• 1.41W linear transmit power for 64 QAM modulation

• May be operated with video

• High reliability, state of the art design using microstrip MMIC and surface mount technology; conservative

component derating and 100% burn in help ensure reliable operation

• Low power consumption

1.4 System Features

• Local control via LCD and 4 soft touch push buttons

• Remote frequency and level agile via RS232/RS485

• Fully phase locked synthesized oscillators referenced to a TCXO for exceptional frequency stability

• Durable design is reflected in the stainless steel chassis and lexan labels

• International internal switching power supply (100 to 240 VAC)

• Front panel displays IF/RF power
