CorelixRF offers the CRF-PA-40000M54000M-120W for engineering teams that need high-power output in the 40 GHz to 54 GHz mmWave range. The local datasheet identifies this model as a GaN SSPA platform for high-power RF systems, with use cases including test and measurement instrumentation, communication systems, RF interference system-level testing, and aerospace control systems.
The amplifier delivers 120 W rated output power across 40-54 GHz with 52 dB minimum small-signal gain. The datasheet lists -10 to +10 dB small-signal gain flatness, up to 15 dB gain control range, 50 ohm input impedance with 1.5:1 VSWR, -20 dBc harmonics, and -60 dBc spurious reference. These values make the CRF-PA-40000M54000M-120W a serious rack-level amplifier for high-power mmWave test environments.
The RF interface is designed around a 1.85 mm-F front-panel input and WR19 waveguide output. That output path should be reviewed with the entire test setup, including waveguide sections, directional couplers, high-power loads, antenna feeds, adapters, and calibration plane. For this power level, the RFQ should clearly state where output power must be measured: at the amplifier output flange, after a transition, or at the final test port.
The system uses AC 220 V +/-10%, 50/60 Hz power and forced-air cooling in a 19-inch 6U form factor. Control interfaces include RS485 and LAN. The datasheet lists real-time temperature monitoring, real-time current monitoring, optional forward/reverse power monitoring, optional input power detection, and protection functions for over-temperature, over-drive, over-voltage, and VSWR alarm behavior.
For buyers comparing mmWave power amplifier options, this model should be treated as an integrated RF system component. The 6U chassis, forced-air cooling, waveguide output, remote control, and monitoring requirements should be considered before procurement. A complete technical review should include rack space, airflow, duty cycle, source drive, output reference plane, and control protocol.
