1.85 mm V RF Connectors Guide: Types, and Structure
What are 1.85 mm V RF Connectors?
The 1.85 mm V RF connector is a high-performance precision coaxial connector designed for frequencies up to 67 GHz. It features a 50 Ω impedance and a threaded coupling mechanism, ensuring stable signal transmission and secure connections.
It is mechanically compatible with 2.4 mm connectors, but not with 2.92 mm, 3.5 mm, or SMA connectors due to differences in interface design. This makes it ideal for high-frequency test and measurement applications where accuracy and reliable performance are critical.
1.85 mm V RF Connector Compatibility with 2.4 mm
1.85 mm (V-type) RF connectors are mechanically compatible with 2.4 mm connectors,
allowing precise inter-mating up to 67 GHz.
However, they are not compatible with 2.92 mm (K), 3.5 mm, or SMA connectors due to
different mechanical interfaces.
While the 1.85 mm series maintains a 50 Ω impedance and a threaded coupling mechanism,
mating with incompatible types can cause damage or reflection issues.
Adapters are recommended when connecting to lower-frequency systems.

Using incompatible interfaces can damage the connector and degrade performance, so always verify mating compatibility before use.
3. Select the Right Mounting Type
Choose the connector type based on your application:
PCB Receptacles for board-mounted designs
Cable Connectors for flexible or semi-rigid cables
Adapters for interconnecting different interfaces
Right-angle connectors are ideal for compact layouts, while straight types are suitable for direct connections.
4. Match Cable Type
Ensure the connector matches the cable you are using, such as semi-rigid or low-loss coaxial cables.
Proper matching improves impedance stability and minimizes signal attenuation.
5. Consider Application Environment
For test and measurement setups, durability and repeatable performance are critical.
If the connector will be frequently connected and disconnected, select high-quality precision connectors designed for repeated mating cycles.
