500 Watt Ka Band Airborne TWTA

Polarity hits a high speed performance benchmark with its ultra-lightweight 500W Ka pulsed amplifier. Building upon Polarity’s previous airborne design and high modulation rates, the new Ka band pulsed TWT amplifier can run continuously at rep rates above 1MHz and short bursts at 2MHz. This TWTA amplifier is ideally suited for short range, high resolution radar systems. The POL500 Ka transmitter covers a frequency range of 32GHz to 36 GHz and provides 500 Watts of peak power at 33% duty. This TWTA radar transmitter was designed for either ground mobile or airborne systems.

The TWTA has a strong serial interface that communicates to a military proven MCU. The MCU provides advanced sync and control options and can be easily reconfigured to custom applications. A rich control protocol provides serial RS232/422/485, ethernet, and advanced user-friendly communication for data logging and cost-effective maintenance.

Outstanding thermal design ensures reliable operation from ambient temperatures of -40C to +70deg C. The POL500Ka – P offers a design with industry leading reliability and its power supply design ensures rugged performance that is unmatched. This high efficiency transmitter design meets the demands of today’s complex pulsed microwave radar systems.

The POL500Ka offers a design with industry leading reliability and rugged performance that is unmatched. With more than 40 years of high power supply design experience, Polarity amplifiers continue to lead the industry in weight, efficiency, and performance.
