1.85mm of common millimeter wave connector

1.85 mm connector is a connector developed by HP Company in the mid-1980s, that is, now Keysight Technologies (formerly Agilent). The inner diameter of its outer conductor is 1.85mm, so it is called 1.85mm connector, also called V-shaped connector. It uses air medium, has excellent performance, high frequency, strong mechanical structure and other characteristics, and can be used with glass insulators. At present, its highest frequency can reach 67GHz (the actual operating frequency can even reach 70GHz), and it can still maintain high performance in such ultra-high frequency band.

The 1.85mm connector is a reduced version of the 2.4mm connector, which is mechanically compatible with the 2.4mm connector and has the same robustness. Although mechanically compatible, we still do not recommend mixing. Due to the different application frequency and tolerance requirements of each connector connector, there are various risks in the hybrid connector, which will affect the service life and even damage the connector, which is a last resort.

1.85mm main performance indexes

Characteristic impedance: 50 Ω

Operating frequency: 0~67GHz

Interface basis: IEC 60,169-32

Connector durability: 500/1000 times

 

As mentioned earlier, the interfaces of 1.85mm connector and 2.4mm connector are similar. As shown in Figure 2, at first glance, the differences between them are small and difficult to distinguish. However, if you put them together, you can see that the inner diameter of the outer conductor of 1.85mm connector is smaller than that of 2.4mm connector – that is, the hollow part in the middle is smaller.
