Frequently Asked Questions
Is the QPA1724 a 20W linear power amplifier?
No. The QPA1724 provides approximately 5W linear output power. The 20W rating refers to its saturated output-power capability.
Is the QPA1724 suitable for LEO satellite communications?
Yes. Its 17.3–21.2GHz bandwidth, linear output capability and compact package make it suitable for wideband and multicarrier LEO SATCOM transmitters.
When should the QPA1725 be selected instead?
The QPA1725 is more suitable when the system requires approximately 10W linear output power. Both devices provide up to 20W maximum output and cover the same nominal frequency range.
Does the QPA1724 include an RF power detector?
Yes. An integrated power detector supports output monitoring, calibration and system diagnostics.
Is a QPA1724 evaluation board available?
Yes. The QPA1724EVB is available for RF evaluation and prototype development.
