If the optional ICS is ordered, verify that the switch(es) are installed in the ICS location(s). Otherwise, leave the factory-installed jumpers in the ICS location(s).
Alignment Procedure
To align the return path:

1If the amplifier is powered, remove all fuses before you perform the following steps.

2If necessary, carefully install a return hybrid amplifier.

3Ensure that both hybrid screws are tight. Torque the screws to 10 to 12 in-lbs. Over torque can damage the hybrid.

4Install the design value pad in the return output pad location.

5Install the design value SRE-*-*.

6Verify that the return input pad locations have 0 dB pads (or JXP-ZX jumpers) installed.

7Verify that any remaining return pad locations have 0 dB pads (or JXP-ZX jumpers) installed.

8Verify that the JXP THERM pad location has a 0 dB pad (or JXP-ZX jumper) or a JXP-TH*B installed.

9Set the sweep equipment output level to the amplifier’s design input level. Add insertion point loss.

10If required, change the return output pad and/or SRE-*-*to achieve, as close as possible, a match of the reference level as compared to the node.

11Verify the sweep response of all insertion points if applicable.

12Verify that the pad and SRE-*-*values are similar to the map design values.

You can verify proper return alignment by injecting a carrier, at the design level, into any amplifier at random. Proper alignment is achieved if you observe the reference level at the headend optical receiver output.

Return levels used for alignment are not necessarily operational system levels. These levels vary from system to system due to differences in equipment, architectures and design philosophies.

For an in-depth analysis and discussion of the return path, refer to Motorola’s Return Path Level Selection, Setup and Alignment Procedure.

Closing the Housing

Before you close the housing:

1Record all pertinent information as required.

2Secure the electronics chassis in the housing and torque to 18 to 22 in-lbs. This facilitates heat transfer and reduces damage caused by overheating.

3Verify that the electronics chassis cover screws are torqued to 10 to 12 in-lbs.

4Check the condition of the RF and weather gaskets and replace them if necessary.

5If applicable, ensure that the electronics chassis handles are folded down and the cable between the power pack and electronics chassis is not pinched.

RF Amplifier specifications

Motorola RF Amplifiers are integral components in radio frequency applications, known for their reliability and superior performance across various telecommunications platforms. These amplifiers are designed to enhance the strength of radio signals for wireless communications, ensuring clear and stable transmission over longer distances.

One of the key features of Motorola RF Amplifiers is their ability to deliver high linearity. High linearity is crucial in reducing distortion in transmitted signals, which is especially important in applications like mobile communications, where signal clarity can significantly affect call quality and data transmission. This characteristic allows for greater efficiency and effectiveness in systems where multiple signals are present, such as in densely populated urban areas.

Another significant aspect of Motorola RF Amplifiers is their broad frequency range. These amplifiers can operate across various bands, from VHF to UHF and even higher frequencies, making them suitable for diverse applications ranging from public safety communications to broadcast services. The versatility in frequency response adapts to the needs of different devices and systems, making them a preferred choice for engineers and manufacturers alike.

The technology underpinning Motorola RF Amplifiers includes advanced materials and integrated circuit designs that allow for higher thermal efficiency and reduced power consumption. This is particularly important in battery-operated devices where energy efficiency leads to extended operational life. Additionally, the compact packaging of these amplifiers ensures that they can be easily integrated into a variety of devices without requiring excessive space.

Motorola also places a strong emphasis on durability and ruggedness in their RF Amplifiers. Many models are engineered to withstand harsh environmental conditions, making them suitable for outdoor installations and challenging applications. Their ability to perform consistently in extreme temperatures, moisture, and vibration enables deployment in critical infrastructure contexts like base stations and emergency services.

Moreover, Motorola RF Amplifiers typically include built-in protection features, such as thermal shutdown, over-voltage protection, and automatic gain control. These safeguards enhance the longevity and reliability of the amplifier, reducing the need for maintenance and offering peace of mind to operators who rely on these systems.

In conclusion, Motorola RF Amplifiers are characterized by their high linearity, broad frequency range, energy efficiency, and rugged durability. With advanced technologies and features that ensure optimal performance, they continue to meet the demands of contemporary wireless communication systems, solidifying Motorola’s reputation in the RF engineering field.
