Summarizing our long year’s experience in manufacturing and developing high reliable microwave source and the feedback of customers, after elaborate design and improvement, we successfully manufacture GMG-2020P 2KW programmable control microwave source. It possesses the high reliability, excellent performance, stable working situation, and convenient operation.

This system adopts PLC program control, which has the features of high control accuracy, perfect stability, and easy operation.

This system adopts the separated structure of control cabinet and power head, which is propitious to connect different models of waveguide system.

The user can connect it with corresponding reactors. It can be broadly used in scientific research and manufacture in high technology area, such as MPCVD of various kinds of film (diamond, diamond-like, and so on); microwave ECR system, microwave plasma source, and microwave exquisite ceramics sintering.

Features:

a) Use the magnetron 2M-259 as microwave generator with 2kW output power.

b) transmitting system: can optionally match according to the customer’s requirement, such as circulator, short load, electrical three-pins modulator, and so on.

c) Control system: adopts PLC control, being capable of controlling microwave output power, reacting power and working time.

General Specification:

1) Frequency: 2450MHz +- 25MHz

2) Power supply: 380VAC+-5%, 50Hz, three phase, four wire

3) Power output: 200W - 2000W continuous adjustment.

4) Power Consumption: 3.1 kW,

5) Power stability: +-1%(at the 2kW output power level).

6) Power display: Digital displays the power output, reflected power,

operating time and the input data.

7) Transmitting system: This power source is suggested to match with WR-340 transmitting system, which consists of circulator, dummy load, tuner and others, so that it can be working stable with a various load.

8) Interlock protection: Power overload, lack of water and others.

9) Microwave leakage: Follow the International Standard.

10) Output waveguide: WR340 with FD340 standard flange.

11) Cooling water flow: 0.15-0.2 m3 / h, clean and soft water

Water temperature: Water inlet: < 25C; Water outlet: < 35C

12) Size: Control Cabinet 750(L) x 500(W) x 650(H) mm,

Magnetron Head 350(L) x 340(W) x 280(H) mm.

Founded in 1958, Guoguang Electric Co., Ltd. Chengdu. is one of the Soviet Union's aids 156 key projects during the 1^st Five-Year plan, and also a comprehensive factory dedicated in manufacturing of microwave electron. In October of 2000, the factory is reorganized into a share-holding corporation that set foot in science research, manufacturing and trading. The headquarter and the manufacturing base are situated in the state-level economic and technological development zone of Longquanyi District, Chengdu city. The manufacturing base area is 133,340m² and the total area of structure is 80,000m². The total asset of the company is nearly 900 million RMB and net asset is 600 million RMB. Over 1100 staff members have been employed and over 30% of them are medium and high ranking technicians.

The main business scope of the company is: Research and production for all kinds of microwave electron vacuum parts, solid microwave devices and microwave encapsulation, vacuum contactor and breaker, vacuum chamber, switch gear, aircraft kitchen appliance(including train meal-trolley) , exhaust carts, all kinds of non-standard machinery and electrical equipment, vacuum gauge, vacuum measurement instruments, appliance of microwave energy, microwave source, medical laser appliances, etc. The products have been sold as far as overseas market and achieved great contributions for the national defense and scientific research work.

The company has been attaching much importance to the development of technology and equipment renewal since its establishment. To guarantee the production, the company has introduced much advanced equipment from U.S., France, Austria, Italy, Germany, etc. Our company has a complete internal matching capacity, besides the developing and researching of components, devices and overall unit, we can do raw material analysis, precision component processing, ceramic manufacturing and sealing, cathode manufacturing, surface treating, reliability and environment test.
