C Band 80/100W Satellite Block Up‑Converter BUC 5.85‑6.725GHz Lightweight RF Transceiver

ZD-BUC-5.85/6.725G-80/100W
This lightweight C Band Satellite Block Up‑Converter BUC is available in 80W and 100W power grades, covering standard and extended C‑band frequency range of 5.85‑6.725 GHz. Optimized for multi‑carrier and multi‑transponder operation, it supports IF input of 950‑1525 MHz or 950‑1825 MHz and accepts a 10 MHz external reference signal. The 80W version reaches 49 dBm rated output power while the 100W model delivers up to 50 dBm.Weighing only 5 kg, this RF transceiver performs reliably within ‑40℃ to +60℃ wide temperature range. Built 1:1‑redundant‑ready hardware supports optional hot or cold backup kits. It is equipped with SNMPv2 M&C interface and WR137‑G waveguide output, suitable for fixed, portable and transportable satellite terminal deployments.
