5G Base Station Isolator MIM Parts

Introduction of Metal Injection Molding 5G Base Station Isolator MIM Parts

With the accelerated development of 5G network construction, in order to achieve seamless coverage of the entire 5G network, the UDN networking method of "macro base station + small base station" needs to be adopted. According to industry estimates, the number of 5G macro base stations will be more than twice that of 4G macro base stations, while the number of 5G small base stations will be 2-3 times that of 5G macro base stations.

Dapu Communication has a core circulator & isolator R&D team with a strong R&D experience of more than fifteen years on average. It has achieved a full range of high-power and low-power coverage in circulator & isolator products, which can meet the needs of Acer. The application requirements of different scenarios of stations and small base stations. Dapu Communication is a long-term strategic cooperation unit of Zhongwei Precision, which provides Dapu Communication with a lot of metal injection molding process products for 5G parts.

Here we will focus on the application of Dapu Communication's full range of low-power circulators & isolators in small base stations:

5G small base stations provide in-depth coverage in the form of lamp pole stations and indoor substations, which requires small base stations to have the characteristics of small size, light weight, low power consumption, and wide frequency. Therefore, there are special requirements in the selection of corresponding devices. Size is an important consideration. Therefore, among the circulator & isolator products, the low-power patch series is especially suitable for the application scenarios of small base stations. Including 7mm*7mm, 5mm*5mm, 4mm*4mm, etc., it can basically meet the application requirements of small base stations in various scenarios.

1、Features of Low Power Circulator & Isolator

1) Small size

The minimum size of the current general high-power circulator & isolator is: d*h=Φ7*5.8mm, while the low-power circulator & isolator is L*W*H=5*5*2mm, or even smaller;

2) Light weight

The weight of a single product is about 0.2g;

3) Low material cost

Material cost is more advantageous than high-power circulator & isolator;

4) Wide frequency band coverage

At present, the general high-power circulator & isolator Φ7mm frequency band covers 1.8GHz~5GHz, while the low-power circulator & isolator can cover 0.6GHz~5GHz.

4. Typical application of low power circulator & isolator in 5G small base station

Circulators & isolators have always been the core devices in wireless communication systems, and their key indicators will affect the overall performance of communication equipment. All have high requirements. Relying on Dapu Communication's strong R&D strength in the field of circulator & isolator, Dapu Communication is one of the few in the low-power circulator & isolator product series that can provide a variety of sizes, and can do well in key performance index parameters. In the future, Dapu will continue to introduce new products to meet the diversified needs of the market.
