Spacek Labs offers three categories of frequency sources.
Gunn Oscillators - These are a relatively inexpensive stable source that can be fixed, mechanical or varactor tuned.
Frequency Synthesizers - A lower frequency synthesizer is multiplied, amplified and filtered to produce a clean and stable band of frequencies in the millimeter-wave frequency range.
Phase-Locked Sources - Single frequency Phase Locked Oscillators in Ku band are multiplied, amplified and filtered to produce a clean and stable output in the millimeter-wave frequency range.
