The listed operating supply is +28V~ +32V. The RF connector is SMA-F. The stated mechanical specification is 1 26 * 47.5 * 23 mm (without connectors), ≤230g. Temperature protection is listed as Over 80℃ protection，with open circuit protection.

Technical Specifications

Integration Considerations

Plan the power supply, RF connections and thermal management around the electrical and mechanical specifications shown above. Contact QHXK for configuration options and documentation.

1.5–200 MHz, 5 W model overview

This model is listed for 1.5–200 MHz, with CW output of at least 37 dBm (approximately 5 W) and customized gain of at least 37 dB. The table specifies gain flatness of ≤1±1 dB, input VSWR of ≤1.6, input power of 0±2 dBm and maximum input of +6 dBm. These values should be checked against the current datasheet for the exact configuration.

Electrical and RF integration notes

The listed working-voltage range is +28 V to +32 V and operating current is ≤1–2 A. The table separately gives a 28 V/3 A supply reference; confirm the recommended power-supply capacity with QHXK before finalizing the DC design. The RF connector is SMA-F, and the PTT port is listed as default off with 3.3–5 V for on. The published table also lists over-temperature protection above 80°C and open-circuit protection.

Because the specified range is broad, do not assume that gain, output or matching is identical at every frequency. Confirm performance at the required operating points and review the specified thermal arrangement; the listing states that a radiator should be installed for power-amplifier testing.

Selection checklist

• Confirm the complete required frequency span within 1.5–200 MHz.
• Verify the CW output target and customized gain requirement.
• Match the RF source to the listed input-power range and maximum input.
• Confirm the DC supply recommendation, current draw and PTT logic.
• Check SMA-F cabling, mounting and cooling instructions.

Frequently asked questions

Is 37 dBm approximately 5 W?

Yes. 37 dBm is approximately 5 W. The product table specifies CW output of ≥37 dBm; confirm the test conditions and guaranteed limits in the current datasheet.

Does the module provide the same performance across 1.5–200 MHz?

Not necessarily. Review the manufacturer’s frequency-dependent data and confirm the required output and gain at the intended operating frequencies.
