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.

1000–2000 MHz, 20 W model overview

This RF power amplifier is specified for 1000–2000 MHz, with CW output of at least 43 dBm (approximately 20 W) and customized gain of at least 43 dB. The published table lists gain flatness of ≤2±1 dB, input VSWR of ≤1.8, input power of 2±2 dBm and maximum input of +6 dBm.

Supply, control and RF interface

The listed working voltage is +28 V and operating current is ≤2.8 A. The table also provides a 28 V/4 A supply reference; confirm the required supply capacity and operating conditions with QHXK for the ordered configuration. The RF connector is SMA-F. The PTT port is listed as default off, with 3.3–5 V for on, and the table specifies over-temperature protection above 80°C and open-circuit protection.

For a 1000–2000 MHz design, check performance at the actual frequencies required by the system. The frequency range alone does not establish flat output power or gain at every point. Confirm the output rating, input-drive range, matching and cooling arrangement using the current datasheet.

Before selecting this module

• Confirm that the required band is fully within 1000–2000 MHz.
• Check the CW output definition and customized gain requirement.
• Verify the RF input level and maximum permitted drive.
• Confirm the 28 V supply design, current margin and PTT control.
• Review the SMA-F interface, thermal installation and mechanical drawing.

Frequently asked questions

What does 43 dBm mean in watts?

43 dBm is approximately 20 W. The listing specifies CW output of ≥43 dBm; verify test conditions and guaranteed performance in the current datasheet.

Can this module cover frequencies outside 1000–2000 MHz?

The published range is 1000–2000 MHz. Do not assume operation outside that range without written confirmation from the manufacturer.
