Abstract: In view of the radio frequency system some special space miniaturization layout demand, we implement a Ka-band point-frequency phase-locked frequency source，by a hybrid integrated technology of combining sampling phase-locked and frequency multiplier-amplifier. This paper introduces the designed Schemes of the use of ADF4016 frequency synthesizer, voltage-controlled oscillator, MSP430 Multi-Service Processors and so on to develop X-band point-frequency phase-locked sources, and then realizes the research purpose of Ka-band point-frequency sources through the link schemes including the frequency multiplier, amplifier, filter and so on. The measurement result of the Ka-band point-frequency phase-locked frequency source shows that the technical specifications of Ka-band point-frequency source operating frequency, phase noise, and output power agree well with the design.
