This paper presents the design and fabrication of a compact 4-8GHz sweep frequency source at C-band with a hybrid frequency synthesizer technology. With DDS used as PLL’s reference, the frequency step size is as small as 3×10-4 Hz and the measured 1 kHz offset phase noise is-91.79dBc/Hz at 4GHz. This frequency sweep source has advantages of wide bandwidth, low phase noise, small frequency step size, low spurious, fast tuning speed, small size and low power consumption. So it is suitable for wireless hand-held test equipment and communication equipment.

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.

With the increasing demand of millimeter-wave (MMW) communication, the performance of its frequency synthesizer has high requirements. In this paper, a multiple conversion mechanism, which used hybrid frequency synthesis technique is presented. Some key modules include linear frequency-modulated generator, agile, and low phase noise local oscillators (LOs), automatic gain control, receiver front-end circuit, and MMW LO circuits are discussed and simulated to verify correctness of the mechanism. The experimental results show that, spurious is better than −65 dBc, phase noise is no more than −80 dBc/Hz@1 kHz, and the maximum frequency-hopping time is <1.8µs.
