Block upconverter, also known as (BUC) is used in uplink of satellite signals.
It converts a given band of low frequencies to a higher frequency typically needed for uplink work. Latest block upconverters converts frequencies from L band to S band, C band, x band. KU band and Ka band.
Most block upconverters use phase-lock loop local oscillators-a control system that generates related output signal- that calls for an external 10MHz frequency reference to maintain correct transmit frequency stability.
Block up converter (BUC) is basically used along with the Low Noise block down converter (LNB) which make up for the “transmit” part of the system and the “receiving” part respectively.
Block upconverters used in remote locations have 2 to 4 watts power in Ku Band frequency and 5 watts in C Band.
Block up converters and Low Noise Block converters are used in conjunction in VSAT-very small aperture transmission-systems used for bidirectional internet access via satellite.
BUC or Block upconverters is a block-shaped device that is assembled with an OMT-orthogonal mode transducer-fitted to the feed horn facing the parabolic reflector dish.
Block up converters for airborne applications have to be skillfully designed to meet the strict quality and performance levels of commercial airlines and military sectors. These devices, often, have to perform in the most challenging environments and therefore have to be highly reliable. There is an additional demand on these devices from the airborne industry for requirements like Size, Weight and Power (SWaP). Block Upconverters for have to meet all these stringent requirements in totality.
Raditek offers many types of Block up converters on its website.
