The primary goal is to be able to roughly calibrate some signal sources in the 8.4GHz to 10GHz range with known calibrated equipment at lower frequencies. I have a Tektronix RSA306B Spectrum Analyzer, but a receiver with the appropriate coverage would work.

Signal paths (really need a diagram!)

Uncalibrated 10.5 GHz Source : 30dB Attenuator : High Pass Filter : Mixer RF IN Calibrated Oscillator at 5GHz : Frequency Doubler : Mixer LO IN Mixer IF Out : Spectrum Analyzer (centered at 500MHz)
