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.

Type selection guide: Hengwei Microwave Electronic Co. Ltd. undertakes customization of different kinds of fixed frequency oscillator (dot frequency sources) / sampling phase-locked dot frequency source products.
The structure and packaging form can be designed according to the requirement of the user.
Note 1: 8 GHz frequency adopts high precision external reference source;
Note 2: 8 GHz frequency adopts built-in reference source;
Note 3: 18 GHz frequency adopts high precision external reference source;
Note 4: 18 GHz frequency adopts built-in reference source.
Note: because the phase noise is related to output frequency, the above specifications are only typical ones. For specific values, please confirm with us, but they can basically satisfy the theoretical value of -6dB/oct.
