The 150W C-band BUC is a rugged, compact solid state amplifier (SSPA) with integrated block up converter (BUC) suitable for fixed and mobile satellite communications with high data rate or multicarrier requirements. The 150W C-band BUC is an outdoor, environmentally sealed product that can be mounted close to the antenna feed to reduce waveguide loss.
The BUC-C150 is a professional-grade 150 W C-band Block Upconverter (BUC transmitter) engineered for high-power satellite uplinks, MVDS broadcasting, DSNG and DVB-S/S2 systems requiring high linearity and multicarrier operation. With its PLL stabilized 4900 MHz LO, built-in 10 MHz reference and GaN solid-state amplifier design, the BUC-C150 ensures excellent frequency stability, high spectral purity and superior linearity necessary for modern broadcasting and satellite communication networks.
Operating with an IF input range of 0.95-1.525 GHz and delivering RF output in the 5.85-6.425 GHz band, the BUC-C150 upconverter guarantees wide-band coverage suitable for global C-band applications. The 150 W output power (Plinear 49 dBm, Psat 52 dBm) and ≥76 dB gain make the BUC-C150 ideal for demanding satellite uplinks, high-data-rate multicarrier transmissions and mobile broadcasting units.
The unit integrates N-type IF input and WR137-G waveguide flange output with a fully matched transition for low-loss RF performance. Advanced spectral filtering achieves in-band spurious ≤ −50 dBc, out-band ≤ −60 dBc, LO leakage ≤ −40 dBm and image rejection ≥60 dB, ensuring clean DVB transmission with minimal interference.
