Wideband 200W-class GaN CW amplifier
The MPA6-18G-4438 uses GaN MMIC devices and power combining to cover 6–18GHz in continuous-wave operation. Its specified saturated output is at least 53dBm, approximately 200W, and its power gain is at least 53dB. This wideband configuration is intended for integration into microwave RF equipment with a suitable waveguide load and forced-air cooling path.
Supply and enclosure configuration
The source lists 220V AC in its power-supply table, but identifies connector J3 as a +28V DC input. These describe an unresolved system/module supply distinction: confirm the delivered supply arrangement before ordering or connecting power. The +28V DC interface must not be treated as an AC inlet. Housing dimensions are customized, and IP66 capability is an optional custom requirement rather than a standard enclosure rating.

Control interface and reference image
The control interface provides enable and attenuation bits of 0.5, 1, 2, 4, 8 and 16dB. The supplied specification prohibits no-load operation at the RF output. The input-drive row is omitted because its source unit is ambiguous. No mechanical outline was supplied for this model: the image is an AI-generated enclosure concept, not a photograph or a confirmed production layout. Connector positions, dimensions, supply arrangement and environmental options are agreed for the final configuration.
