Description
Specialty Microwave 573874-1 LNA Control Panel SATCOM 120V Dual PSU Rack Mount
The Specialty Microwave 573874-1 is a rack-mount Low Noise Amplifier (LNA) control panel designed for SATCOM ground station systems. Built and co-labeled by AIL / Eaton Advanced Electronics, this unit provides centralized control and status monitoring for a three-LNA switching matrix, supporting both local and remote operation modes from a single front panel.

Applications
LNA control panels of this type are central to SATCOM ground station antenna systems, where multiple low noise amplifiers are deployed in redundant configurations to maintain continuous satellite link availability. The controller manages which LNA is active on the signal path — switching between primary and backup amplifiers either automatically or on operator command — while providing real-time status via the front-panel LED matrix. Local/Remote capability allows the panel to be operated directly by a technician at the rack or driven from a remote monitoring and control system. This type of equipment is used in fixed and transportable satellite earth stations for commercial, government, and defense communications, as well as broadcast uplink facilities. The dual power supply design and redundant LNA switching architecture reflect the high-availability requirements typical of professional SATCOM infrastructure.
This Specialty Microwave 573874-1 LNA Control Panel was pulled from a working SATCOM environment and has been inspected at our facility. Both power cords were connected and the unit was powered on. All front-panel LEDs illuminate correctly when the lamp test button is pressed. The front and rear switches engage their respective mechanisms and respond as expected. No testing of the LNA switching outputs could be performed. The chassis shows light surface wear consistent with rack service use; overall cosmetic condition is good. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
