1.0 GENERAL INFORMATION
1.1 System Overview
The MA4367 is a frequency-agile commercial quality transmitter for MMDS applications. Advanced design permits full
frequency agility over the 2505 to 2681 MHz frequency band while still maintaining a phase noise specification which exceeds
the requirement for 64 and 256QAM. The MA4367 is a Vecima 4000 series system which includes an upconverter, power
amplifier and power supply/control module housed in a single chassis. The MA4061B is a frequency agile MMDS upconverter
in a modular circuit card designed for use with the Vecima MA4000 Series. The MA4070C is a solid state, fixed gain power
amplifier for MMDS applications. Each MA4000 card chassis with common MA4011B or MA4012B power supply can contain 1
MA4061B and 1 MA4070C Power Amplifier in a 4U rack mount configuration. This advanced, cost-effective transmitter offers
high performance, flexibility and space efficiency.
1.2 MA4061B Module Features
• Front panel selectable output frequency from 2505 to 2681 MHz 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 MA4070C Module Features
• 4 W linear transmit power for 64 or 256QAM 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 or optional SNMP
• 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) or DC supply (-36 to –60 VDC)
• Front panel displays IF/RF power
