Ultra Stable Millimeter Wave Oscillator Intended for Space Project "Phobos - Grunt"

The ultra stable oscillator (USO) is intended for Phobos (satellite of Mars) orbit investigation. The USO instrument would be delivered to Phobos by Russian spacecraft. The USO instrument would irradiate signals at two harmonically related frequencies: 33.6 GHz and 8.8 GHz. The irradiated power would be about 1 W for each channel.
