Mobile World Congress 2021 was held in Barcelona, Spain from June 28 to July 1, 2021.  5G technology, cloud computing and artificial intelligence are still the focus of the event. Affected by the COVID-19 , the exhibition adopts the coexistence of offline and virtual exhibition halls, with a total of about 1,000+ online and offline exhibitors and about 30,000 participants.

Dapu Telecom participated in the event as scheduled. In the exihibition, Dapu featured Clock Products (crystal oscillators, clock modules, clock servers), Chip Products (RTC, Buffer, IEEE1588(PTP), All Silicon Oscillators, PHY) and RF Products (circulators, isolators), among which the RTC series products and low-power isolators attracted a lot of attentions.

Real time Clock (RTC)： it can realize the clock timing function and provide an accurate time reference for the electronic system. It is widely used in many fields such as communication, electric power, IoT, security, medical, automobile, industrial control, consumer electronics and so on.

Dapu’s RTC has the following main advantages:

1. Completely independent intellectual property rights, all technologies and IP are independently developed;

2. The high-quality supply chain is adopted, with stable quality and sufficient production capacity, and has been supplied to top customers in the industry;

3. Various RTC can meet the differentiated needs of customers in various industries;

Dapu’s RTC series：

Low-power circulator/isolator: 5G uses UDN networking with "Micro site + small cell" for coverage. Low-power isolators are not only used for macro base stations for isolating between stages, but also especially suitable for small base stations. Because small base stations are limited size and low consumption, it has no more demand for power but higher request for volume of isolators. The market of small base stations has great prospects, and the demand of isolators with small size and low power are increasing year by year.

Dapu’s low-power circulator/isolator has the following advantages:

1. Small size: 5*5*2mm;

2.Low power: 10W;

3. Low cost of material: less than 1/2 of the Φ7mm products;

4. Wide band frequency: 0.6GHz~5GHz.

The structure of Dapu low power circular/isolator is divided into the top cover, magnet, SL+ferrite, Chip C, PCB, Case and other parts, simple structure, high performance, the main features lead the industry.

Clock Chip, Clock Module, and RF Products, Dapu Telecom will stick to the strategy of these three product lines and continuously provide high-quality, cost-effective products and overall solutions for the global customers.
