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.

1100–1280 MHz, 100 W model overview

This model is specified for 1100–1280 MHz, with CW output of at least 50 dBm (100 W) and customized gain of at least 49 dB. The published table lists gain flatness of ≤1±1 dB, input VSWR of ≤1.6, input power of 1±1 dBm and maximum input of +6 dBm.

RF interfaces and electrical requirements

The RF interfaces are listed as RFIN-SMA-F and RFOUT-SMA-F. The working-voltage range is +28 V to +32 V, with operating current listed as ≤9–10 A. The table gives a 28 V/12 A supply reference; confirm supply sizing and test conditions for the exact version before integration. The PTT port is listed as default off, with 3.3–5 V for on.

The product table also specifies over-temperature protection above 80°C, open-circuit protection, spurious output of ≤−65 dBc, harmonic level of ≤−25 dBc and an operating-temperature range of −40°C to +55°C. Review the original table and current datasheet together when defining acceptance limits.

Engineering checks before ordering

• Confirm that the required operating frequencies fall within 1100–1280 MHz.
• Verify CW output, customized gain and gain-flatness requirements.
• Check RF input level and the separate SMA-F input/output connections.
• Confirm DC supply capacity, PTT logic and protection interfaces.
• Review cooling, mechanical drawing and guaranteed operating-temperature limits.

Frequently asked questions

Is 50 dBm equal to 100 W?

Yes. 50 dBm corresponds to 100 W. The product table identifies this as a CW output rating; confirm the test conditions and guaranteed limits in the current datasheet.

Are the RF input and output connectors separate?

Yes. The listing identifies RFIN-SMA-F and RFOUT-SMA-F. Follow the manufacturer’s interface drawing for connector assignment and installation.
