Ka Band Integrated Dual Frequency LO Subsystem

In the paper an integrated dual fequency LO subsystem will be presented that provides LO signals for a converter system that downconverts signals in the 18 - 40 GHz range (subranges 18 - 26; 26 - 34; 34 - 40 GHz) into the 4 - 8 GHz band (1). The LO frequencies for these conversions are 26 GHz, 30 GHz, and 34 GHz. One LO subsystem generates two (of the above mentioned three) frequencies, phaselocks them to the provided references and multiplexes them to the LO OUT port of the subsystem.
