4 W Ku-band block up-converter with LO of 12.8 GHz BUC-Ku04-12.8 v2 is designed for MVDS TV broadcasting systems application in accordance with DVB-S/S2 or DVB-C standards (use “Customized” button to choose needed parameters) and operates with up to 25 carriers. BUC-Ku04-12.8 v2 has output flange of PBR120 type and can be used with regular radio-relay link (directional) or broadcast (sector and OMNI) antennas. BUC-Ku04-12.8 v2 supports all modulation types up to 32APSK and 256QAM (you may choose the modulation type while filling the “customized equipment” form). BUC-Ku04-12.8 v2 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-Ku04-12.8 v2 is locked by PLL with internal frequency reference). BUC-Ku04-12.8 v2 provides 13.75 – 14.75 GHz output frequency range (bandwidth in Ku-band) for 950-1950 MHz input frequency range (bandwidth in L-band).
BUC-Ku04-12.8 v2.0 is a 4 W Ku-band Block Upconverter designed for DVB-S/S2 broadcast uplinks, MVDS TV distribution and satellite repeater stations. With solid-state reliability and a clean output spectrum, it is ideal for demanding broadcasting networks.
The BUC-Ku04-12.8 v2.0 uses a PLL-locked 12.8 GHz local oscillator with ±2 ppm frequency stability and low phase noise of −85 dBc/Hz @10 kHz. Supporting DVB-S2 modulation formats up to 32APSK and 256QAM, it provides high-quality transmission with low IMD3 and excellent linearity.
