e2v's Coupled-Cavity TWTs 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:

• Velocity tapering and multiple depressed collectors are used to achieve high efficiency, low prime power, and to minimise heat rejected to the cooling system.
• The range consists of tubes of rugged metal/ceramic construction, designed for mobile military environments. They employ high µ shadow grid modulation suitable for modern multi-function radars.
• They produce peak powers up to 1MW, bandwidths up to 10%, and cover frequencies from 5GHz to 35GHz.
• The Coupled-Cavity TWTs are capable of peak powers from tens to hundreds of kilowatts, with up to 10% duty cycle.
• e2v's Coupled-Cavity TWTs are in service in all types of ship, airborne and ground-based mobile radar systems.
• Long-range surveillance radars Naval surveillance & tracking radars for fire control systems
• Airborne multi-mode & surveillance radars Ground-based acquisition & tracking radars for fire control systems.
