e2v STA3318 KU1AN 180W Ku-Band TWTA Uplink Power Amplifier WR75 — Tested Working
This listing is for a high-performance e2v Stellar STA3318-KU1AN Ku-Band TWTA (Travelling Wave Tube Amplifier), designed for professional satellite uplink applications.
This antenna-mount TWTA delivers up to 180 W RF output power, supports the full 13.75–14.5 GHz Ku-band uplink range, and features the rugged StellarMini™ outdoor enclosure for reliable operation in demanding environments.
The STA3318 series is widely used in teleports, SATCOM terminals, VSAT hubs, SNG/DSNG uplinks, broadcast systems, and any Ku-band high-power RF chain requiring stable, linear output.
This model is the KU1AN version, meaning it operates as a pure Ku-band TWTA without internal BUC. The signal is fed directly at Ku-band through the WR75 waveguide interface, making it ideal for upgrade or replacement in existing uplink RF chains.
