Since the 1960s, China has developed and produced RF connectors from the whole machine factory. In the 1970s, production was carried out by professional manufacturers. In the 1980s, according to the self-reliance policy, the Soviet Union products were mainly used. In the 1980s, international common products were developed and produced using international standards, mainly based on state-owned and collective enterprises. Joint ventures and foreign-funded enterprises. At present, there are hundreds of domestic RF connector manufacturers, but the scale is not large. The production methods of the backbone manufacturers and the production level of the universal connectors are comparable to those of foreign countries.
Faced with problems:
The strength is thin and the scale is too small.
Participation in market competition is outdated, the civilian product market has appeared below the cost price, and there are other unfair competitions.
The sense of globalization is poor and cannot adapt to the needs of the new economic era.
Digitalization and e-commerce management are backward.
There is no RF connector professional in colleges and universities, resulting in a shortage of professionals.
The influx of foreign capital and local production.
Precision connectors and surface mount connectors are backward.
The passive intermodulation problem has not received enough attention.
Miniaturization: With the miniaturization of the whole system, the size of RF connectors is getting smaller and smaller, such as SSMB, MMCX, etc., which is very small.
High frequency: HP has introduced RF connectors with frequencies up to 110 GHz a few years ago. The domestic general product use frequency does not exceed 40GHz. The frequency of the flexible cable is not more than 10 GHz, and the semi-rigid cable is not more than 20 GHz.
Multi-function: In addition to the function of the bridge, it also has the functions of processing signals, such as filtering, phase adjustment, mixing, attenuation, detection, and limiting.
Low standing wave, low loss: meet the needs of weapon systems and precision measurement.
Large capacity, high power: mainly to meet the development needs of the information superhighway.
