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.

2.0 INSTALLATION
CAUTION: This device must be professionally installed.
1 mW/CM The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF fields in excess of the FCC recommended limits.
For more information, refer to the Federal Communications Commission guidelines on radio frequency safety, accessible through their Web site: www.fcc.gov.
2.1 Unpacking the Unit
Carefully remove the equipment from its packing material and set it on a solid surface, such as a table or desk. If it appears damaged in any way, notify the carrier, and keep all packing materials for inspection by the carrier’s agent.
2.2 Operating Environment
The MA4367 system includes an active cooling fan tray which forces cooling air from the bottom through to the top of the chassis. For adequate ventilation, a space of 1U (1.75”) should be left in the rack, directly above the MA4367 chassis for warm air exhaust. It is designed to operate at temperatures ranging from 10 to 40 operation at excessive temperature accelerates the deterioration of components. For this reason, measures should be taken to prevent the build up of excessive heat in the rack.

C (50 to 104oF). As with all electrical equipment,
Antenna Requirements
The MA4367 is operated with a user-supplied antenna. Please consult table 2.2A for further information. Mount the antenna according to the manufacturer’s instructions.

( Caution: The antenna(s) used for MA4367 Agile MMDS Transmitter system is to be installed in an
outdoor fixed environment. The antenna is to be mounted on an outdoor permanent structure with a minimum separation distance of 1.5 meters between the antenna elements and nearby persons.
RF exposure compliance is addressed at the time of licensing.
( The maximum recommended antenna gain is 18 dBi.
ma4367_ml_03_sd Approved: B.G. 9
2.3 Power Requirements
The equipment is supplied with either an AC international auto-ranging internal power supply which allows it to be powered from any 100 to 240 VAC; 50 to 60 Hz source, or a DC supply capable of operating from –36 to –60 VDC.
Check the total current consumption of all equipment on the same line before applying power to the MA4367 system. Avoid sharing a power source that feeds heavy motors or other equipment, which require large current drains.
2.4 Rack Mounting
The MA4367 system is designed for standard rack mounting in a 19” equipment rack. It requires 4U (7.00”) of vertical rack space. It should be installed in a rack allowing access to the back of the unit. The upconverter should be isolated from strong RF radiation emanating from local equipment in the rack. Power line transients that may cause damage to the unit should be avoided. For adequate ventilation, a space of 1U (1.75”) should be left in the rack, directly above the MA4367 chassis for warm air exhaust.
2.5 Module Installation/Replacement
1. Power off the chassis using the rear panel power switch
2. Disconnect the RF cables from the rear of the corresponding module
3. Using a screwdriver, loosen the corresponding front panel captive screws until the module is free to pull forward
4. Insert the replacement module and retighten the front panel captive screws
5. Turn on the power switch
6. Configure the output frequency and IF/RF levels. Note that after power cycle, the frequency of the MA4061B needs to be re-entered in order for the power detectors on the MA4070C to lock on properly.
7. Reconnect the rear panel RF cables

is the Mode Information Line. It shows the settings for the currently selected module. The possible operating modes depend upon the currently selected module (See Section 3.2, Front Panel Operating Modes for a detailed description of the available modes).
The second line on the display
is the Status Information Line. The Status Line is divided as follows:
The two leftmost characters are “mX” where X is replaced by the currently selected module address. When used with the MA4070C Power Amp Module or the MA4070C Power Amp Module, they can be installed as shown in Diagram 3.1A.
