1.85 mm Adapter --- ZOMWAVE

What is essential for any current electronic product? There must be many answers to this answer. Today we are going to discuss one of the indispensable components, that is, 1.85 mm adapter. Of course, for a product design engineer, choosing a 1.85 mm adapter has become a very important part of his work.  

Now in some large companies, there are dedicated 1.85 mm adapter and cable engineers, who will be responsible for the selection and verification of all 1.85 mm adapters. Of course, smaller companies may be selected and validated by a Structural Engineer (ME) or an Electronic Engineer. Obviously, when the interface rate of the product is very high, traditional structural engineers or ordinary electronic engineers can no longer judge whether the selected 1.85 mm adapter can meet the requirements of product design. At this time, more professional engineers are needed to complete this work, so SI engineers or hardware engineers who understand high speed are involved in the selection of 1.85 mm adapters and cables. So how to choose the connector? Something to watch out for? What is the impact on the product?

The selection of the 1.85 mm adapter is mainly based on two major directions, the first is the structure, and the second is the electrical performance.
In terms of structure, the 1.85 mm adapter must first meet the function of connection, so it conforms to the structural design, and the pins correspond to pins one by one.In terms of electrical performance, the 1.85 mm adapter needs to meet the requirements of impedance, insertion loss, return loss, far-end crosstalk, near-end crosstalk, delay and so on.
