TL08XO - Communications & Power Industries

Outdoor TWTAs
850 W Peak Power Outdoor TWT Amplifier
Built for Outdoor Applications
Provides up to 420 watts of linear power in a rugged and
compact weatherproof package, digital ready, for satellite
uplinks in the 7.9 to 8.4 GHz frequency band.
Cost Effective and Efficient
Mounting at the antenna improves performance through
minimized cable losses and saves cost in system design.
Employs a high efficiency, dual-depressed collector helix
traveling wave tube and an integral linearizer, further
reducing operating costs.
Designed and built to survive in extremely adverse
environmental conditions and features increased cooling
margin for longer life. CAN-Bus architecture improves
reliability and noise immunity. Optional LifeExtender™
significantly increases TWT lifetime.
Simple to Operate
User-friendly microprocessor-controlled logic with
integrated Ethernet computer interface. Digital metering,
pin diode attenuation and optional integrated linearizer for
improved intermodulation performance. Optional SNMP
facilitates high level M&C integration.
Easy to Maintain
