Satellite uplink performance can be ruined by weak conversion or unstable gain, leaving you with dropped links and costly downtime. The Advantech Wireless ARUN-70L-WE, C-Band Block Upconverter (BUC) solves this by turning L-Band IF signals into a clean, powerful RF output for C-Band satellite systems, giving you reliable connectivity when it matters most.
Advantech Wireless ARUN-70L-WE, C-Band Block Upconverter (BUC) - Precise Up-Conversion for Critical Links
The unit tackles the common problem of signal loss during up-conversion, which can degrade data rates and increase error rates. By delivering consistent gain, low spurious emissions and fine frequency control, it ensures your satellite link stays strong and clear, even in demanding environments.
Usages of Advantech Wireless ARUN-70L-WE, C-Band Block Upconverter (BUC)
Designed for professional satellite communication rigs, this BUC fits into rack-mounted RF chains, supporting terrestrial-to-satellite gateways, broadcast uplink stations and remote sensing platforms that require stable C-Band transmission.
Benefits of Advantech Wireless ARUN-70L-WE, C-Band Block Upconverter (BUC)
You gain high output power of +10 dBm for robust link margins, while the 25 ± 1 dB conversion gain boosts signal strength without adding noise. The 0.7 dB gain flatness over 40 MHz keeps performance uniform across your channel plan. Fine 0.1 dB gain steps let you optimise each link, and the -55 dBc spurious level protects adjacent channels from interference.
