BUC-Ku40 is designed for MVDS TV broadcasting systems application in accordance with DVB-S/S2 and operates with up to 25 carriers. BUC-Ku40 has output flange of PBR120 type and can be used with regular radio-relay link or broadcast antennas. BUC-Ku40 supports all modulation types up to 32APSK. BUC-Ku40 has the best linearity parameters to ensure the stability of the output frequency and low IMD3 level (these parameters are very important for high quality modulation, therefore the local oscillator of BUC-Ku40 is locked by PLL with internal frequency reference).
