Designed for high-performance RF applications, this high power amplifier stands out with its wide frequency coverage of 8-18GHz, making it a versatile choice for scenarios that demand reliable signal amplification—especially when paired with a digital RF modulator to enhance signal integrity. It supports both CW and pulsed input signals, with an input pulse width range from 50ns to CW, and requires only 0-3dBm RF input drive to deliver a saturated output power of 44±1dBm, ensuring robust performance even in demanding setups involving a digital RF modulator.
 
With input and output VSWR both high power amplifier maintains stable signal transmission, which is critical for systems relying on a digital RF modulator to process and transmit high-frequency signals. It integrates multiple protection functions: reverse polarity protection, over-temperature protection (powers off when temperature exceeds 85°C and restarts when below 65°C), over/under-voltage protection (shuts down if voltage is over 36V or under 24V), and over-current protection (turns off when current surpasses 10A), guaranteeing safe operation for both the amplifier and connected components like a digital RF modulator.
 
Operating at 28V/5A, it features a fast power ON/OFF time of high power amplifier seamlessly complements a digital RF modulator to meet high-frequency signal amplification needs.
