300W High Power Ka Band Block Up Converter 27.5‑31GHz GaN RF Amplifier for Satellite Communication
Built for demanding satellite communication projects, this 300whigh powerKa band Block Up‑Converter adopts mature GaN amplifier technology to deliver stable RF transmitting performance. Supporting 27.5‑31 GHz RF output and 950‑1950 MHz IF input, the unit accepts a 10 MHz external reference, with optional high‑stability internal reference for enhanced frequency precision. This high powerKa band hardware reaches rated output power of 54.8 dBm, fitted with amplifier overdrive protection to safeguard core circuits. It achieves outstanding phase‑noise and spurious suppression, well‑suited for high‑order modulation satellite links.Engineered for extreme field conditions, the 300wGaN amplifier operates reliably from ‑40℃ to +60℃. It integrates comprehensive M&C functions including Ethernet, SNMPv2 and serial interfaces, and supports optional redundancy setups for uninterrupted service. Weighing 30 kg with compact mechanical structure, this robust Ka band transmitter is a solid RF solution for mission‑critical satellite ground terminal deployments.
