2 W Ku-band block up-converter with LO of 11.8 GHz BUC-Ku02-11.8-v2.0 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-Ku02-11.8-v2.0 has output flange of PBR120 type and can be used with regular radio-relay link (directional) or broadcast (sector and OMNI) antennas. BUC-Ku02-11.8-v2.0 supports all modulation types up to 32APSK and 256QAM (you may choose the modulation type while filling the “customized equipment” form). BUC-Ku02-11.8-v2.0 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-Ku02-11.8-v2.0 is locked by PLL with internal frequency reference). BUC-Ku02-11.8-v2.0 provides 12.75 – 13.75 GHz output frequency range (bandwidth in Ku-band) for 950-1950 MHz input frequency range (bandwidth in L-band).
BUC-Ku02-11.8 v2.0 is a professional-grade 2 W Ku-band Block Upconverter designed for DVB-S/S2 uplinks, MVDS broadcasting and mobile satellite applications. With 2 W at P1dB and ≥53 dB gain, this Ku-band BUC transmitter ensures robust, stable transmission for demanding multicarrier systems.
Featuring a PLL-locked 11.8 GHz LO, the unit guarantees ±2 ppm stability and excellent phase noise performance (−85 dBc/Hz @10 kHz). It supports advanced modulation schemes up to 32APSK and 256QAM, ensuring reliable operation for DVB-S/S2 broadcasting environments.
✅ Engineered for outdoor deployment
