C-Band BUC description

BUC is an abbreviation of "Block Up-Converter".   It is attached direct to the transmit waveguide flange of the filter/feed assembly of a VSAT dish, used for satellite communications, particularly in areas of heavy rainfall such as the tropics, or where the minimum possible outage time during very heavy rain is desired.  The IFL cable from the indoor equipment supplies DC power, a 10 MHz frequency reference plus the actual signals to be transmitted.  The signals to be transmitted are in a 575 or 300 MHz wide band, between 0.95 - 1.525 GHz or 1.1 - 1.4 GHz in the cable, which will be up-converted in the BUC to C band (5.85 - 6.425 GHz or 6.725 - 7.025 GHz for the INSAT satellite), using a local oscillator mixer frequency of 4.9 or 5.625 GHz.  So, Output frequency (GHz) = Input frequency (MHz) + 4.9 GHz or Output frequency (GHz) = Input frequency (MHz) + 5.625 GHz (INSAT).  The mixer local oscillator is locked to the 10 MHz frequency reference.

These C band BUCs come direct from the NEXGENWAVE who is the manufacturer and you will pay them directly and receive your BUC direct from them.  When you complete the enquiry form your contact details and the type and quantity of BUCs required will be sent to them.  They will then give you a quotation including shipping costs.   You may be responsible for additional taxes, VAT, customs duties etc. Your contract is direct with the BUC manufacturer, Nexgenwave, address: Si-Cox Tower #621, Sangdaewon 513-14, SeoungNam City, 462-120 Korea.  Tel: +82-31-777-9912    Fax: +82-31-777-9916    Your payment MUST be received and fully cleared before any goods will be dispatched.

RF Hazard safety notice:  Radio frequency hazard warning sign: Non ionisisng radiation

The output of the BUC is microwave power.  Although 2, 5 or 10 watts is less that in a domestic microwave oven (typically 800 watts) it has heating power and you must not allow it to heat or burn the human body.  It is most important is to avoid the microwave power getting to the human eye which has a lens which maybe destroyed by the heat.  There is no blood going through the lens to cool it down.  So never look into a waveguide and when the antenna system is working and do not put your head between the feed window and the dish or into the cylindrical beam which goes towards the satellite.
