200W Pulsed Q Band TWT Amplifier
Pulsed and CW Transmitter
Polarity hits a high speed performance benchmark with its ultra-lightweight 200W Q band 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 300kHz and short bursts at 600kHz. This TWTA amplifier is ideally suited for short range, high resolution radar systems. The POL200Q a transmitter covers a frequency range of 43.5 GHz to 45.5 GHz and provides 200 Watts of peak power from 1% to 100% 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 +75deg C. The POL200Q 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 POL200Q 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.
