1 W Ku-band block up-converter with LO of 9.75 GHz BUC-Ku01-9.75 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-Ku01-9.75 v2 has output flange of PBR120 type and can be used with regular radio-relay link (directional) or broadcast (sector and OMNI) antennas. BUC-Ku01-9.75 v2 supports all modulation types up to 32APSK and 256QAM (you may choose the modulation type while filling the “customized equipment” form). BUC-Ku01-9.75 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-Ku01-9.75 v2 is locked by PLL with internal frequency reference). BUC-Ku01-9.75 v2 provides 10.7 – 11.7 GHz output frequency range (bandwidth in Ku-band) for 950-1950 MHz input frequency range (bandwidth in L-band).
BUC-Ku01-9.75 v2.0 is a DVB-S/S2 Ku-band Block Upconverter engineered for satellite uplinks, MVDS networks and mobile broadcast platforms. It integrates a fixed 9.75 GHz PLL local oscillator, ensuring frequency precision, low phase noise and stable operation with demanding modulation formats like 32APSK and 256QAM.
This solid-state Ku-band transmitter delivers 1 W output at P1dB, ≥47 dB gain and automatic level control with 25 dB dynamic range. The integrated 10 MHz reference simplifies synchronization in DVB-S/S2 broadcast systems, making the BUC-Ku01-9.75 v2.0 ideal for high-stability Ku-band uplinks.
