DRO frequency sources | Sampling and phase-locking dot frequency source | Wideband frequency synthesizer |
Brief introduction of the products:
The fixed frequency oscillator / sampling phase-locked dot frequency source serial products developed and manufactured by Hengwei Microwave Electronic Co Ltd. adopt advanced micro-electronic packaging technology.
This series of sampling phase-locked dot frequency sources adopt the technology that combines sampling frequency discrimination and dielectric oscillator technology, which make full use of the features of high reliability, high stability and very low background phase noise in sampling frequency discrimination technology. All of them have high reliability, high stability of output frequencies and very low phase noise. This series of frequency sources have 2 kinds of references: built-in reference and externally fed reference.
Application of the products:
This series of products are widely used as frequency sources in the microwave communication systems, which is the optimum solution for microwave dot frequency local oscillator.
