Ultra Wideband 20-6000MHz 100W Power Amplifier with DDS Signal Generator

ZD-DPA-X/XM-100W
This high-performance ultra wideband power amplifier delivers 100W output power across an exceptionally wide 20-6000MHz frequency range, making it ideal for military, aerospace, and advanced RF testing applications. The integrated DDS Direct Digital Synthesis signal generator ensures precise frequency control, allowing users to generate stable, low-phase-noise signals with programmable modulation for complex signal scenarios. Engineered for reliability, the amplifier features high efficiency ≥42% and software-adjustable power levels 10W-100W, with an ALC Automatic Level Control range of ≥30dB for dynamic power management. Advanced thermal protection, including an active cooling system (heat sink + fan), ensures stable operation even under continuous high-power conditions. Additional features include real-time monitoring (power, temperature, VSWR, RS485 control interface, and comprehensive protection against overvoltage, overcurrent, and signal reflection VSWR ≤1.35. Compact and rugged, this ultra wideband amplifier is perfect for electronic warfare, signal jamming, and wideband communication systems requiring both high power and precision frequency synthesis.

Monitoring FunctionDescriptionRemark
Amplifier part setting parametersAmplifier switchTurn the amplifier on or off
Alarm switchEnable and disable the alarm function
Downlink Power ControlThe maximum output power of the power amplifier can be set, the adjustment range is ≥20dB, and the high, medium and low power
levels can be set
Amplifier over temperature alarmThe high temperature power amplifier shutdown threshold can be set, the power amplifier temperature exceeds 85 degrees, it will
automatically shut down; 65 degrees will automatically restore
Amplifier overpower alarmThe actual power value is 2dB higher than the downlink ALC start control threshold and close
Power amplifier standing wave alarmWhen the standing wave detection of the power amplifier is greater than 4, the power amplifier is automatically turned off
Amplifier overcurrent alarmWhen the detection current of the power amplifier exceeds 12A, the power amplifier is automatically turned off
Amplifier under-power alarmWhen the power amplifier detection power is less than 33dBm, an under-power alarm is displayed
Amplifier overvoltage alarmWhen the power amplifier voltage exceeds 32V, the power amplifier will automatically shut down
Amplifier undervoltage alarmAmplifier voltage
