The Block Up-Converter Ku-band 4W Verion 2 (BUC-Ku04 v2) designed for operation in MVDS/MITRIS TV broadcasting systems according to standard DVB-S/S2 or DVB-C and operates up to 25 carriers. This device has flange PBR120 output and could be used with regular RRL or broadcast antennas. Supported modulation types are up to 32APSK, 256QAM. Stability of the output frequency and IMD3 level are very important, to ensure the modulation, so the local oscillator is locked by PLL with an internal frequency reference. The device has best linearity parameters to ensure the IMD3 level. The BUC-Ku04 v2 provides any 1000 MHz in Ku-band by order output frequencies for 950 – 1950 MHz input frequencies.
