Product Detail

This product is a high power RF amplifier module with an integrated digital RF modulator, utilizing DDS (Direct Digital Synthesis) technology to deliver stable 150W output across the 5.75–5.9GHz band. It offers exceptional frequency accuracy and flexible power control, supporting multiple operating modes including fixed-frequency, wideband sweep, and multi-sub-band switching with a maximum bandwidth of 500MHz. This makes it well-suited for modern wireless systems that require frequency agility and multi-function integration.

The module excels in RF performance with in-band ripple ≤2.5dB and input/output VSWR below 1.5:1, ensuring high-fidelity signal transmission. Users can adjust output power in real-time via software with an ALC range ≥10dB, adapting to varying application needs. Comprehensive monitoring and protection features are also included, such as temperature detection (-40℃ to +100℃), voltage and current monitoring, and alarms for over-power, mismatch, and under-voltage, significantly enhancing system robustness and service life.

The combination of high power and DDS frequency synthesis makes this module particularly suitable for applications requiring high dynamic range and frequency precision, including military communications, radar signal generation, electronic warfare, and automated RF testing. The built-in digital RF modulator further extends its functionality, supporting complex modulation schemes for modern software-defined radio (SDR) and intelligent communication systems.
