Commodore A
Fixed Class A
- Best suited to
- A stable waveform and a defined, repeatable operating point.
- Integration
- Allow for Class A quiescent power and cooling requirements.
Select from four power classes, with frequency-band models across 20 MHz–7.5 GHz. Each model covers its specified band; the full range is not available from a single module. Standard models operate at 28 V DC.
The following power classes and band options apply to both Commodore A and Commodore AB.
| Power class | Frequency range | Models | Key Application |
|---|---|---|---|
| RF HPA — 10 W | 20–7500 MHz | 9 | Comms, EW, radar subsystems |
| RF HPA — 25 W | 20–6100 MHz | 6 | Ground-based RF systems |
| RF HPA — 50 W | 20–6100 MHz | 5 | Vehicle-mounted, defence |
| RF HPA — 100 W | 20–4200 MHz | 4 | High-power RF, RS-485 ctrl |
Select a power class to view the available frequency-band models. 150 W and 200 W modules, broadband multi-octave amplifiers and custom configurations are available on request.
Operating approach
Both lines offer 10, 25, 50 and 100 W power classes with the same band-specific options across 20 MHz–7.5 GHz. Choose the bias approach that fits your application.
Each module covers its specified band. Confirm output power, gain, efficiency and distortion for the selected frequency, bias, waveform and cooling conditions.
For selection advice, send your band, output power, waveform, duty cycle, DC supply and cooling constraints. Include linearity targets such as EVM or intermodulation where relevant.
