Coupled–Cavity Traveling Wave Tubes

CCTWTs are ideal for compact, reliable, high performance multi-function radars. They have high gain, high efficiency, shadow grid modulation, and PPM (Periodic Permanent Magnet) focusing:

  • Designed for military environments

    • Rugged metal/ceramic construction

    • High µ shadow grid modulation

  • Velocity tapering and multiple depressed collectors achieving:

    • High efficiency

    • Low prime power

    • Minimise heat rejected to cooling system

  • Peak powers up to 1MW

  • Bandwidths up to 10%

  • Frequency range: 5GHz to 35GHz

The Coupled-Cavity TWTs are capable of peak powers from tens to hundreds of kilowatts, with up to 10% duty cycle. Typical applications include:

  • Ship, airborne and ground-based mobile radar systems

  • Airborne multi-mode surveillance radars

  • Naval surveillance radars

  • Tracking radars for fire control systems

  • Ground-based acquisition

  • Mobile military environments
