LNR-L3 UPC-100 Uplink Power Control


Categories: , , Tag: Manufacturer: ,


The Uplink Power Control model UPC-100 was originally manufactured by LNR but later acquired by L3 and so we list the product by both manufacturer’s names.

A UPC works with the 70MHz output from a Beacon Receiver or Down Converter and measures the satellite downlink strength – using this information it automatically adjust the output power of the attached amplifier(s) ensuring that the satellite receives a constant power level from the ground station.


The UPC-100 can be equipped with several attenuators as seen in the photograph, We typically sell one attenuator per UPC, but more are available if required.
