THz sources and detectors
Carcinotrons
The BWO (backward wave oscillator), also called a carcinotron, is a vacuum tube used to generate radiofrequency radiation up to THz frequencies. Carcinotron life is limited due to lamp filament wear. Spectral width of the line is around 20MHz.
| Frequency range | Power | |
| OV-67 | 350-540 GHz | 48-200 mW |
| OV-74 | 506.9-~599.7 GHz 684-728.9 GHz | 0.5-6 mW |
| OV-44 | 840-1000 GHz | 20-100µW |
| OV-100 | 1034-1250 GHz | 1-3 µW |
VDI AMC sources
Electronic sources of radiation in the 70GHz – 1THz frequency range are composed of frequency synthesizers and Amplification and Multiplication Chains (AMC). Radiation polarisation is lineair.
