CorelixRF introduces the CRF-PA-36000M50000M-20W as a 36 GHz to 50 GHz solid-state mmWave power amplifier for engineers building higher-frequency RF test systems, communication test platforms, RF interference system-level test benches, and aerospace control environments. The amplifier is based on GaN SSPA technology and is designed for applications where output power, waveguide interface planning, monitoring, and rack-level integration all need to be reviewed together.
Operating across 36-50 GHz, the CRF-PA-36000M50000M-20W provides 20 W rated RF output power with 45 dB minimum small-signal gain. The local datasheet lists small-signal gain flatness of -8 to +8 dB, up to 15 dB gain control range, 50 ohm input impedance with 1.5:1 VSWR, -20 dBc harmonics, and -60 dBc spurious performance reference. These figures make the model relevant for mmWave benches that require more than low-level signal boosting.
For RF interface planning, the amplifier uses a 1.85 mm-F front-panel input and WR22 waveguide output. That combination should be reviewed before the mechanical and measurement setup is finalized. At 36-50 GHz, the adapter path, waveguide run, coupler selection, load rating, antenna feed, and calibration plane can all affect the useful power delivered to the device under test.
The amplifier is supplied as a forced-air 19-inch 3U system and operates from AC 220 V +/-10%, 50/60 Hz. The datasheet lists RS485 and LAN control interfaces, real-time temperature monitoring, real-time current monitoring, optional forward/reverse power monitoring, and optional input power detection. Protection functions include alarm and fault behavior, over-temperature protection, over-drive protection, over-voltage protection, and VSWR protection/alarm functions.
This configuration is especially suitable when an engineering team needs a controlled mmWave amplifier platform rather than a bare RF block. Test and measurement users should define the output reference plane, frequency window, waveform type, CW or pulse operation, duty cycle, and required monitoring data. System integrators should also confirm rack airflow, service access, control protocol, and whether GPIB programmable control is needed.
