5100–5900 MHz, 100 W model overview

This model is specified for 5100–5900 MHz. Its published CW output is ≥50±0.5 dBm, with customized gain of ≥48 dB and gain flatness of ≤2±1 dB. The table lists input power of 2±2 dBm, input VSWR of ≤1.7 and an SMA-F RF connector.

The listed working voltage is +28 V to +30 V and working current is ≤9–10 A. Other published details include a 3.3–5 V PTT on-level, over-temperature protection, and an operating-temperature range of -30°C to +55°C. The stated dimensions are ≤197×93.5×26.5 mm without connectors, with a listed weight of ≤650 g. A radiator is specified for power-amplifier testing.

Integration checklist for the 5.1–5.9 GHz band

Verify performance across the required portion of the band rather than relying on the center frequency alone. Confirm the output-power tolerance, gain flatness, RF input level, connector, supply and thermal conditions in the current datasheet. Mechanical clearance should account for connectors and the required radiator.

• Confirm the required frequencies are within 5100–5900 MHz.
• Check CW output and customized gain for the ordered configuration.
• Verify +28–30 V supply capacity and the current requirement.
• Confirm SMA-F connection, mounting and thermal management.
• Review test curves and operating-temperature limits.

Frequently asked questions

What is the nominal power represented by 50 dBm?

50 dBm corresponds to 100 W. This product lists a CW output of ≥50±0.5 dBm; confirm how the tolerance is applied in the manufacturer’s current datasheet.

Does the 5100–5900 MHz range guarantee flat output?

No. Frequency coverage does not by itself guarantee identical output or gain throughout the band. Review the published curves and guaranteed limits.

For a nearby high-frequency option, compare the 8.8–9.6 GHz, 50 W RF power amplifier. See the wideband vs. narrowband comparison and RF PA selection guide, or browse the RF power amplifier module range. Contact QHXK for documentation.
