Outdoor TWTAs




REQUEST A QUOTE
Known worldwide for dependability and long life, our antenna-mounted Traveling Wave Tube Amplifiers (TWTAs) are designed for the most rugged outdoor operational requirements. They eliminate the need for a separate amplifier shelter, reduces the distance between amplifier and antenna feed horn eliminating long waveguide runs, and with forced air cooling allows reliable operation over extended temperature ranges.

Air-Cooled TWTAs

Comtech TWTAs offer high efficiency and high linearity in compact air-cooled packages. They are ideal for fixed and transportable satcom systems.

Liquid-Cooled TWTAs

Our SuperCool™ family of products will resolve all your hub system heat load issues with reliable and quiet liquid cooling.

Outdoor Multi-Band TWTAs

Some of our most rugged products, our Tri-Band Amplifiers are a perfect match for any fixed or transportable application.

Liquid-Cooled TWTAs

Known worldwide for dependability and long life, our antenna-mounted Traveling Wave Tube Amplifiers (TWTAs) are designed for the most rugged outdoor operational requirements. They eliminate the need for a separate amplifier shelter, reduces the distance between amplifier and antenna feed horn eliminating long waveguide runs, and with forced air cooling allows reliable operation over extended temperature ranges.

Liquid cooling is available across the high-power end of the amplifier product-line, including: the 1250W Ku-band and DBS-band products, all 750W products, and the 500W and 250W Ka-band amplifiers. Reference cooling systems have been developed, and Xicom engineers are available to assist customers understand and specify liquid cooling systems that are the ideal solution for their satcom uplink requirements.

Broad spectrum of SuperCool™ liquid-cooled products

From C-band to V-band all high power outdoor TWTAs are available with liquid cooling.

Benefits of liquid cooling

The SuperCoolTM family of amplifiers has many practical advantages over traditional air-cooled amplifiers including reduced heat load in hubs; flexible and more compact installation; ease of service and maintenance; higher reliability; ambient noise reduction; and gain stability over ambient temperature.

The new Comtech Xicom design incorporates integrated cooling channels in the amplifier baseplate, external to the sealed high voltage and RF circuitry compartment, with drip-free connections. Elimination of the need for air flow provision dramatically simplifies hub layout and design and provides more space for maintenance operations and additional equipment.
