Understanding the Difference between Low Power Indoor Block Up Converter (BUCs) and High Power Outdoor BUCs Mounted on the Transmitting Antenna

When it comes to broadband connections for government, commercial, military, or infrastructural industry, the major technological advancements that come top include block up converter (BUC). With their distinctive functions and roles to play.

Block up converters (BUC) are used extensively in those military and commercial satellite systems that deploy transponders of C, Ku and Ka-band as they offer high-end performance and can easily support both fixed as well as portable terminals.

The Indoor BUC low power output is typically fed a short distances over coax cables or waveguide to a High Power Satcom Amp mounted on the rear or frame of the Satcom Antenna.

The Outdoor BUC gets its feed directly from a satcom modem (typically indoors). It is combined with an amplifier and after converting L Band signal from the modem amplifies the signal before feeding the Antenna. For very high power Systems they are tube-based (TWTA), most are solid-state amplifiers. They comprise intermediate-frequency amplifier, mixers, with low-phase noise, and DC-power supply.

These Bucs can range in power levels dependent on Frequency. Examples are:

    C Band 2 to 700Watts SSPA

    X and KU Bands 2 to 1200 Watts

    Ka Band 1-15Watts Watts

All these BUC’s are available from Raditek and are capable of providing powerful performance at affordable prices.
