Key selection points for the 7.7–8.5 GHz, 50 W model
This model is specified for 7700–8500 MHz, with CW output of at least 47 dBm and customized gain of at least 46 dB. The published table also lists gain flatness of ≤2±1 dB, input power of 2±1 dBm, input VSWR of ≤1.7, an SMA-F RF connector, and an operating-temperature range of -30°C to +55°C.
The listed working voltage is +28 V to +30 V. The table specifies a 3.3–5 V PTT on-level and states that a radiator is required for power-amplifier testing. Confirm the final supply-current requirement, mounting arrangement and thermal conditions against the latest datasheet for the exact configuration.
Before selecting this RF amplifier
- Confirm that the complete required operating band falls within 7700–8500 MHz.
- Check the CW output rating and customized gain against the required system values.
- Verify the RF input level, SMA-F connection and PTT control interface.
- Confirm supply capacity, heatsink/radiator provision and operating temperature.
- Request the current mechanical drawing and test report before design release.
Frequently asked questions
Is 47 dBm approximately 50 W?
Yes. 47 dBm is approximately 50 W. The product table states a CW output of ≥47 dBm; confirm the test conditions and guaranteed limits in the current datasheet.
Is the listed gain a fixed standard value?
The listing labels the gain specification as customized. Confirm the gain required and the value guaranteed for the ordered configuration with QHXK.
For broader selection criteria, read the RF power amplifier selection guide and the wideband vs. narrowband RF amplifier comparison. Compare it with the 8.8–9.6 GHz, 50 W RF power amplifier, or browse the RF power amplifier module range.
To request the current datasheet or a configuration review, contact QHXK. Confirm that the intended RF operation is authorized under applicable regulations.
