MCA-111 

Modular Headend Amplifier System

For modern cable headends and hubs, our Modular Headend Amplifier System, Model MCA-111, is perfect for applications such as headend laser transmitter drivers or signal power boosters. It includes from one to a maximum of four amplifiers in a 1RU 19" chassis. Various gain amplifiers can be mixed in a single frame and may include amplifiers for return, as well as for forward path applications.

Datasheet

The amplifiers are easily accessible from the front chassis and are powered with two built-in power supplies connected in redundant configuration. Each of these power supplies is capable of supporting the full load of four amplifiers.  In the unlikely event of a single power supply's failure, you can replace it without interrupting service, increasing the system's reliability. 

FEATURES:

• Excellent input and output return losses: minimum 20dB (50-870MHz) with typical values as high as 24dB to 26dB, helping to maintain proper matching between these amplifiers and other equipment connected to them.

• High output signal level, excellent frequency response and distortion characteristics.

• Alarm circuitry constantly monitors the powering of each amplifier, output of each power supply, and temperature inside the chassis. The monitoring signal is transmitted through the DB-15 connector at the back of the chassis.

• Front panel LEDs allow for visual monitoring of each amplifier power status, cooling fans on/off condition, and power supply module.

• Plug-in attenuator and equalizers at the input and output of amplifiers, giving the operator capability to achieve required gain and slope for a particular application.

• Low noise figure.

• Optional test ports available.

• Chassis and amplifier housings are designed for optimum heat dissipation.

• Highest density in the industry with up to four amplifiers in 1RU 19” chassis for efficient usage of available rack space.
