Precision at High Frequencies: Choosing Between 2.92 and 1.85 Vertical Launch PCB Connectors

You might not be able to use high-frequency RF or microwave equipment correctly if you don't connect them right. 2.92 and 1.85 vertical launch PCB connectors are used for fast, sensitive part connections. What's different about them, though?

 

Understanding the Frequency Range of 2.92 Vertical Launch PCB Connectors

You can use the 2.92 vertical launch PCB connector if you need a connection that works well at frequencies up to 40 GHz. A lot of people use it in radars, phones, and lab tests. Its design strikes a good mix between speed and longevity, which makes it perfect for most high-frequency PCB needs that aren't very high.

Why the 1.85 Vertical Launch PCB Connector Excels in Ultra-High Frequency Applications

The 1.85 vertical launch PCB connector is the best choice for frequencies higher than 40 GHz, up to 67 GHz. This link is almost lossless, and it is very accurate at millimeter-wave frequencies. The connection unites military, scientific, high-tech, and other professionals.

Key Differences Between 2.92 and 1.85 Launch Styles

Both connections have a vertical launch design that cuts down on signal reflection and makes performance better. The primary difference is in how big they are and how often they can work. The 1.85 mm connection can work at higher frequencies than the 2.92 mm variant because it has tighter tolerances and a smaller interface.

Insertion Loss and VSWR Comparison for 1.85 and 2.92 Connectors

Both connections have low insertion loss and high VSWR. At higher frequencies, though, the 1.85 vertical launch PCB connector keeps the signal better than the 2.92 mm kind. 1.85 mm is the clear winner for signal routes that need a lot of power.

 

Use Cases for Each Connector Type: When to Choose 2.92 vs 1.85

If you're working in the 18–40 GHz band, especially for commercial or general RF systems, you should use a 2.92 vertical launch PCB connector. If you need to do very accurate work over 40 GHz, the 1.85 vertical launch PCB connector is the best choice for top-notch performance.

Mounting Considerations for Vertical Launch PCB Connectors

Screw-mount flanges make it easy to install both types of links without soldering, so they are a great choice for thin or delicate PCBs that cannot tolerate solder heat.
