BUC-K-1-23.55 is designed for MVDS TV broadcasting systems application in accordance with DVB-S/S2 or DVB-C and operates with up to 25 carriers. BUC-K-1-23.55 has output flange of PBR260 type (in accordance with WR34) and can be used with regular radio-relay link (directional) or broadcast (sector and OMNI) antennas.
BUC-K-1-23.55 supports all modulation types up to 32APSK and 256QAM. BUC-K-1-23.55 has the best linearity parameters to ensure the stability of the output frequency and low IMD3 level. BUC-K-1-23.55 has input frequency range of 950-1450 MHz (L-band) and provides 24.5-25.0 GHz output frequency range (K-band).
