The Block Up-Converter C-band 4W (BUC-C04 v2) is designed for operation in MMDS TV broadcasting systems according to DVB-S/S2, DVB-C or DVB-T standards and provides up to 25 carriers output. This device has integrated matched CWT and can be used with regular RRL or broadcast antennas. Supported modulation types are 16APSK, 256QAM or COFDM. The local oscillator is locked by PLL with internal frequency reference and has the best linearity parameters to ensure the stability of the output frequency and low IMD3 level – very important parameters for high quality modulation. The BUC-C04 v2 provides 4000 – 4200 MHz (or any 200 MHz in C-band by order) output frequencies for 470 – 670 MHz(other UHF or L-band option by order) input frequencies.
