Low Phase Noise

A Ka-band carrier generator using phase-locked loop (PLL) frequency synthesizer is presented in this paper. The design uses integer-N PLL chip PE83336 as the important hardware support. The key idea of generating Ka-band frequency signal with low-phase noise is to generate a high-quality X-band frequency signal using PLL frequency synthesizer and employ a frequency multiplier to deliver the high-frequency output at the desired frequency band. Experimental measurements of the frequency synthesizer demonstrate the excellent performance, which is achieved with the Ka-band output with a frequency resolution of 5.7 MHz and phase noise better than −70 dBc/Hz at 1 kHz.

Low Phase Noise

The frequency synthesizer is an important part of modern communication system. It is widely used in digital communications, satellite communications, remote telemetry, radar, navigation and other fields. For frequency source with low phase noise and low spurious, this paper gives hardware architecture and implementation method circuit realization of the X-band frequency source which use phase locked and frequency multiplier theory. Its main targets are tested. The test results show that the performance of the frequency synthesizer is preferably with lower spurious level and phase noise.
